I think shoultzula sent you an important message: Mvc2 isn’t balanced.
If you really want to talk about a video game that’s balanced without patches or what not, you should look elsewhere. And even then, beta and alpha testing are used for almost all videogames so that they can be ‘patched up’ for final release.
Most of you probably weren’t around the scene when this happened, but SpiderDan and Viscant (among others) posted about beta testing for MvC2 when it first appeared at SHGL. Basically, Doom flight was godly (among other issues).
So in short, your paper’s thesis doesn’t hold much value because all videogames go through phases of testing, and furthermore, MvC2 is a poor example of a game that is balanced. It’s more like, ‘if I shoot 1000 bullets, one of them is bound to hit’ which is what Capcom did by making 50+ characters. Rather than worry about balance testing to the extreme(I mean really, how do you balance when you have teams of 3v3 with 3 kinds of assist per character… it’s an absurd number to try to test every possible combination), you have 40 or so crap characters that get very little tournament time if at all.
Almost anyone in the MvC2 forums could send you a huge list of improvements that could be made on the game. It’s not that users have found ways to make MvC2 balanced, it’s more like ‘just don’t use [xxxx, crap character, captain america, etc.] if you really want to win in a tournament.’
TTT might be a better example. I mean at least you have to be good at EWGF (which is arguably hard to execute well) to be decent. T5:DR is an even better example, but that’s a 2nd release of T5.
If you just want a history of MvC2 for the sake of having a history of MvC2, then check if SRK has some older posts of gamebreaking finds (Sent Unfly, team dynamics with spiral/cable/cyc, etc) and you can even go to alt.games.sf2 for the days when Stilt argued that strider/doom was trash . Mr. Wiz might be able to help you out with getting the older articles about MvC2 and their dates.
