Notes:

I'm not sure this is a good analogy, but here it goes:
Stan/Nintendo: Stan generally the smartest/least dumb of the group, and Nintendo usually makes smart decisions when it comes to making games.
Kyle/Sega: About as wise as Stan, much like Sega, but not always above it all.
Kenny/THQ: Well, THQ went bankrupt, so I guess it kind of "died".
Cartman/EA: Not really concerned about others (in this case, EA doesn't really think about what would please gamers and more about ways to get rich), more themselves and making money.

Personally, I'm neutral towards EA.
