Since the unfinished version of Card Saga Wars is finally getting released(I'd never thought I'd say that), I'll probably download it at some point, but probably after the 12 characters are dropped. Right now they have the first 4 fighters.
Though Mega Man X is a part of those 4, so I'd already have my main for that game. Though Samus, Master Chief and Chrono are also in it(but aren't released quite yet), not to mention all the assist characters.
I think the devs are working on a game that they'll actually make money off of now. Which is good since they are pretty talented.
