Here you'll see some distinct differences between INTP and ENTP.
The INTP is the serious, mastermind...eccentric antisocial genius working behind the scenes building the architecture of the games.
The ENTP is playful, expansive, the "idea guy", creative genius with a keen business sense and nose for entrepreneurship.
What you see is Ti/Ne versus Ne/Ti. Very similar yet very different at the same time. The INTP John Carmack is ultimately the only one that is stick with iD software and set to release a new blockbuster game this year. He stuck to his guns, and quietly mastered his craft. The ENTP got sidetracked with other stuff, always wanted to do something "new" and faded into oblivion.
You'll also see the NT way of being utilitarian and breaking rules. "Borrowing" their companies computers on the weekends to make games on them.
You'll also see the NT need for autonomy and power. Breaking free of that first company and wanting to make their own games.
They also pioneered the entire idea of making a "game engine" (NTP's have a reputation as engineers) and then selling it off to other companies. This was huge, and games today like Call of Duty STILL use a modified version of the engine Carmack built back in the late 90's for Quake 3. Now in 2011, having a "game engine" is common and many different companies license them out.
Even the name of their games are very NTP. Short, to the point, one word titles.
also pioneered "gore" in video games. And took the concept of digital distribution to the next level.
Video games - changed forever through the mind of two NTPs.
