Logical based introversion creates a lot of advantages in gaming.
Introversion creates advantages in anything that would deal with a great deal of thought opposed to a great deal of external action. Like writing, playing videogames, artwork, music, other introverted activities. In the world of computers Logic is definitely more of an asset than emotion.
So, lets break the IT's down more, while keeping the focus on gaming for cash moneys.
S. In my many travels to tournaments and tournament workshops [practice practice practice!!!] those who're Sensing types seem to excel at inputing commands more so than the iNtuitive types. Preferring a senses over ideas, in theory would make it easier to just input the commands and get a feel for it. Also utilizing complex control schemes seems to come with ease to the sensing types [which I almost envy... almost.]
N. This almost envy... So iNtuitive types lack the input and command skill of the sensing types. However they seem to understand the system and engine of the game in a greater detail than the sensing types which makes finding glitches easier. Or understanding the properties of the inputs and knowing better how and when to use the commands.
So... the sensing types don't need as much practice actually doing the moves in a game, but struggle a little more understanding the system, even after they're taught the system. They still must put more effort into learning it [My friend Steve is like this... He often ignores the more complex properties of a game because his input is great enough for him to not need it as much].
The intuitives have to work much much hardest to actually input the moves. What takes a sensing type a few hours to learn, input wise, may take the intuitive a week or longer. However they learn the properties and system of the game a whole lot faster.
P. Perceptive types, I think, are the ones with the clear cut advantage. So, ISTP and INTP would, in my opinion be the best of the best. In fast paced action games anyway [like Marvel vs. Capcom series, streetfighter, soul calibur, etc..]. They react to situations a lot quicker and can change their actions on the fly. Their strategies just aren't always the best. Which isn't a big deal in those games since a lot of times the strategies can be taught and don't need to be thought up on the fly.
J. Judging types are amazing at coming up with on the fly strategies, and preset strategies and contingencies. e.g. while playing fighting games I have about 3 back up plans ready to go. However these strategies are often trumped in fighters by the ability to react on the fly. But, strategy based games [like LoL, WoW, Star Craft, etc..] are a different story. Those games have the tables turning in favor of judging types.
So, P is great on the fly improve [good for fighters and fast paced games]. J is good for strategies [great for anything that requires a lot of planning].
ISTP: Make it stop!!!!
They're very terrifying to play against even if it's a game they've never played before when it comes to fighting games. Almost never makes input errors, will react to your movements constantly, and erratically and often unpredictably shifts gears during the fight, keeping you guessing all the way through. It's a pretty good combination.
INTP: What the fuck just happened, I've been had my mind blown!!
At first seems a lot like the ISTP during a match. Then, they might make a minor input error and you're thinking it's not as bad. Till you realize it's not an error, it's some weird glitch in the game. Then weird things start to happen and you're mind has been blown. Very entertaining to watch.
ISTJ: It's a trap!!!
The oddest of them all. They have many preset combos for many situations that occur often, and very good input. If you get caught in their world you're usually not getting out. Every ISTJ I've played's weakness is their strength at the same time. The constructed world they run will entrap you in an endless beat down, however, anything outside this set strategy seems to completely through off their rhythm. The lesser skill ISTJ's sometimes panic in this state, the others cut their losses and try eventually see a situation they have a set plan to place you back into the world of pain.
INTJ: Evil mastermind
Close to the ISTJ. Only their world of terror often involves the engine of the game rather than perfect input. Often creating situations that limit your options while playing against them. If they're good, the options they limit you to aren't options you want to be left with. The best I've seen will limit you to options like A. Death/brutal beat down B. moving into a position that enables them to limit your options to A. B. and C.[ taking light damage, losing time on the clock, and being put at yet another disadvantage].
