Aim vs. tactics

The skill-level of the higher echelon of a given game player base increases as one or more of the following occurs:

1. The quantity of the player base increases.
2. The maturity in terms of number of played man-hours increases per player.

In regards to 1v1 gameplay, aim and tactics are always important, but which is more important? Let's define the terms first, using my favorite FPS series Quake as the benchmark. The same definitions can be shifted slightly to apply to other popular FPS benchmarks like Counterstrike.

Aim - To direct a weapon towards an intended target.

I, as a player, have to manage my hand-eye coordination in order to move my mouse precisely to the proper pixel space on the screen, taking additional care based on whether I am using a projectile weapon (plasma gun, rocket launcher, grenade launcher) or a hitscan weapon (machinegun, shotgun, lightning gun, railgun). For projectile weapons, there are additional variables on how to manage hand-eye coordination based on the speed or trajectory of the projectile.

Plasma fire spam is extremely quick and straight. Rockets are moderately fast and straight, but also do splash damage so the best risk-to-reward is to hit a player directly on their feet. Hitting a player directly on their feet will often be rewarded with a direct hit and, therefore, maximize the amount of damage inflicted. If the shot is slightly off, the rocket still hits on the ground near the target's feet to inflict splash damage - the closer the shot to the target, the higher the amount of splash damage done. Grenades have an arcing trajectory and are best, like any other weapon, when the shot directly hits the target. Due to the arcing trajectory, they are slightly more awkward to aim and, as a result, are often spammed (shot in great quantity) in order to create higher quantity of risk for the opponent.

Players can respond to projectile weapons by dodging the fire. Different dodging patterns work better on certain player styles over others, but there are generic dodging patterns that tend to work advantageously overall.

For hitscan weapons, the only limitation to hitting your opponent is the requirement to be in line of sight of the opponent. If you can see your opponent, you can hit them.

Conversely, dodging hitscan weapon, on a technical level, is not possible. However, certain dodging patterns play on standard human hand-eye reaction models to trick a player into aiming improperly and missing their shot. Players who have control over their mental game and are never tricked will never miss because of opponent dodging techniques. There's no current player like this though (although some players impressively come close sometimes).

Tactics - A procedure or set of maneuvers engaged in to achieve an end, an aim, or a goal.

In our benchmark case, the goal is to maintain level control or achieve a point by fragging (scoring a gaming kill) your opponent. Tactics are managed for the following reasons:

1. To maintain level control positionally - The player who controls more advantageous positioning has an advantage (in general). This usually means the player with higher ground or better angles has the positional advantage when initiating a player confrontation (a fight).
2. To main level control via item control - The player who controls the more desired item resources (armor, health, weapons, and sometimes ammo) has an advantage.

Tactical advantages can change quickly if item control changes. Additionally, tactical advantages change quickly based on the positional risks taken and positional changes by each player. There's a lot of subtlety involved in tactics.

As games mature the following occurs:
1. Tactics increase exponentially and then flatten out in growth towards maturity.
2. Aim steadily increases for the overall player base.

This allows for more tactical risk to occur as a game matures since players with increasingly good aim can manage more risk. However, an equal opponent can manage the same. So both factors (aim and tactics) are still equally important.

The issue that arises is when aim increases, the power of projectile weaponry gets reduced. This is unavoidable. Aim being equal, it makes sense to use a weapon (in the majority of cases) that cannot be dodged.

This leads to aim being a stronger factor than tactics, if and only if, the damage done by hitscan weapons is greater than or equal to the damage done by projectile weaponry. This is the current state of things in Quake. Rockets and grenades still have their place, but are not as powerful as they used to be. Why?

Again, if a player can manage more damage without caring about dodging techniques, then it makes sense to do so. In turn, when dodging becomes less relevant and hitscan weaponry become overused, tactical intelligence gets put to the wayside, which, in turn, dumbs down the game.

This is part of the reason why I never got hugely into Counterstrike. Everything is hitscan. The saving grace that Counterstrike has is that it is a team game so tactical positioning and timing is still important because you can work with teammates to move opponents into tactically disadvantageous positioning.

So it comes down to how does a game designer balance hitscan against projectile weaponry. I'm not certain entirely, but I think a good start is to never design a hitscan weapon to be as powerful (damage-wise) as a projectile weapon based on common fight patterns. As a disclaimer, I am comparing the common competiting weapons (rocket launcher vs. railgun / plasma gun vs. lightning gun).

I realize I am showing some bias, but I do truly think that tactics make for more tense and interesting games. Otherwise, base competition becomes reduced into a hand-eye coordination competition, which isn't in the spirit of any competitive 1v1 game.

Elevator etiquette

I have a fascination with various quirky social norms. One of these social norms being the standard etiquette present when riding an elevator. Before I move further, I want to disclaim that my elevator etiquette perspective is limited to standard observation of behavioral social norms in the United States.

First, one can observe the body position.
1. Elevator patron #1 enters the elevator, moving to the back left corner position.
2. Elevator patron #2 enters the elevator, moving to the back right corner position.
3. Elevator patron #3 enters the elevator, moving to the front left corner position.
4. Elevator patron #4 enters the elevator, moving to the front right corner position.
5. Elevator patron #5 enters the elevator, moving to the back center position.
6. Elevator patron #6 enters the elevator, moving to the front center position.

The following pattern is observed:
1 5 2
3 6 4

The positioning is not a guarantee, but it is very common. For example, the order and precise positioning of each patron may vary slightly depending on their right or left-centric brain patterns. It can also vary if the patron feels more comfortable in the rear of the elevator to unconsciously shed less attention upon themselves or if the patron feels more comfortable in the front of the elevator, perhaps feeling the need for a more speedy exit. Additionally, I have observed short-lived awkward chaos when the first person who enters the elevator stays in the front-left position to manage the floor-selection buttons.

Why do people do this? I think it's done as a courtesy. An elevator is a compact space designed for quick and, most often, vertical transportation. Due to the cramped space, people unconsciously try to keep as much space from other patrons, maintaining their sense of comfort and personal space.

A given elevator can also host more or less patrons depending upon the size of the elevator. Even when the elevator is crowded, patrons still attempt to position in an ordered manner to maintain as much personal space as possible.

Once positioning is complete, the elevator starts to move. Conversation tends to die down. Again, this isn't a certainty, but it is generally done as a courtesy. A conversation on an elevator is rarely designed for broadcast and, as such, elevator conversation can make any patron who is an outsider to the conversation uncomfortable.

Also due to the close proximity, rarely is direct eye contact managed. Patrons look at the floor number, waiting to exit. Patrons look at the floor, the walls, posters on the elevator walls. They look at anything but each other, again looking to preserve comfort level.

Finally, exiting the elevator is a ritual in itself. Patrons who know they want to exit sooner than other patrons tend to position closer to the door. If not, that patron needs to move through other passengers in order to exit. The repositioning is done almost mechanically, allowing the respective passenger to exit while maintaining and maximizing space between patrons who remain.

If a number of patrons exit the elevator at the same floor, often position will determine the order of exit. Additionally, traditional cultural norms may show where an adult male will defer to other women and children to exit before them as a courtesy.

The entire ritual is really fascinatingly bizarre.

How do you measure?

So, apparently, being a citizen of the United States, I am counter to the times by being a standard user of the Imperial system. You know the Imperial system?

Measurements: teaspoon, tablespoon, stick, inch, foot, yard, furlong, fathom, mile, nautical mile, acre.
Liquid volume: ounce, cup, pint, quart, gallon, and my personal favorite, hogshead (63 gallons)
Dry volume: pint, quart, gallon, peck, bushel
Weight: ounce, pound, stone, ton

I realize I am about to voice a dated opinion, but I will voice it nonetheless. The Imperial system uses a ridiculous amount of terms to describe measurement. The metric system uses basic math prefixes (milli, centi, kilo, etc.) and three main roots (liters, meters, and grams). The Imperial system is a fucked up mess.

The Imperial system was created by the British Weights and Measures Act of 1824. There is also a pseudo-Imperial system of measurement used in the United States. This measurement system is called U.S. Customary and shares many names and measurements with the Imperial system, but not everything. There was a later refinement in 1959 to the original British Weights and Measures Act in order to get more equivalency between the two similar systems.

Here's the thing though. The United Kingdom transitioned to standard metric units via the Unit of Measurement Regulations in 1995. Measuring devices commonly have both metric and Imperial units on them now. A beer is still sold in the pub by the pint. A number of signs are still in Imperial. However, the region is transitioning to metric.

Many probably know metric, but have used it more commonly in the chemistry lab - meters, liters, and grams... oh my.

A number of countries jumped on the Imperial bandwagon because Britain was pretty good at colonizing or exerting its influence back in the day - United States, Canada, Australia, India, Malaysia, New Zealand, Ireland, Antigua, Belize, Burma (Myanmar), Grenada, Guyana, Sierra Leone, United Arab Emirates, and Liberia.

In the past 40-50 years, there has been a push to standardize the world on a system of measurements. This system is known as the metric system. A number of countries have switched or are in the process of switching from the Imperial system to the metric system.

Some countries have not - the United States, Liberia, and Burma (Myanmar). Yes, 3 countries in the entire world have not yet adopted the International System of Units (the metric system) as their primary system of measurement.

A picture is worth 1000 worlds. How about 3 words?

It's time to suck it up and change. I realize it's a pain in the ass, but there is already infrastructure in place to support this on a number of levels. Your measuring cup at home probably has notches for both liters and cups already. Your car's speedometer probably already has measurements for both miles per hour and kilometers per hour.

The main things I will have to get use on a day-to-day basis are noting my weight in kilograms and having a more intuitive knowledge of the Celsius temperature scale. Let's capture the dream.
