Marvel vs. Capcom: Infinite had a cloud of uncertainty going into E3 and one of the factors was rumor of its complete character roster at launch. One of the best words used to describe it was flaccid.
The roster wasn't outright bad, but it wasn't at all an exciting list of characters, almost entirely composed of returning characters from Marvel vs. Capcom 3 who all likely carried the same moves and models as well. But I think I can safely say that when E3 ended, I don't think I've ever seen a game's public image and goodwill die as desperately as MvCI. At least Battleborn was visually distinct.
