Capcom V.P. Christian Svensson was on the Unity Boards today explaining their reason for not rebalancing Marvel vs. Capcom 2, which is being re-released this summer on the XBox 360 and PlayStation 3.
In Marvel vs. Capcom 2 there are a lot of weird match ups and infinites. Are you guys going to fix bugs and rebalance the game?
Sven: There are a few exploitable glitches and bugs being fixed, but by and large we are intentionally NOT rebalancing the game (thus it has no "Remix" as part of its title).
Part of the game's appeal to a large number of fans are the inherent quirks of various characters.
Loads of characters have infinites... the game is practically balanced in its imbalance and there are always going to be matchups that are more or less favorable than others (true of any fighting game).
