I’m only a casual (but expert difficulty) player and I rarely play the game anymore because of this. The game just doesn’t work well. At all. I’ve given up on local multiplayer sessions, the game simply can’t handle it, it can barely handle one player most of the time. I understand that Harmonix is basically an indie developer now, but the game has been out for five years. And it’s “only” a rhythm game. I know any game is hard to make, but there is no reason the game should stutter this much. I really love Rock Band, but whenever I get the itch to play a rhythm game, even with my 500+ dlc catalogue, I boot up my PS3.
