Yeah. Injustice and Killer Instinct are pretty much the only "current" fighters there is (you could count Ultra Street Fighter IV too, but that's just basically an update for a game that came out in 2009 or something). But KI doesn't even have that much content in it right now. Only 8 characters (not including Shadow Jago) and 8 stages (not including Shadow Tiger Lair). Arcade Mode just got added, etc... So good game, just not that much content yet.
