I'm not sure how would take having RockSteady again. The campaign was awesome, the art work was great, and I think they do a real good job. BUT... after seeing the DLC they created for this game, I think they either gave up, or they're getting to be too money hungry. I'm not talking about HQR, that was awesome, but the Robin/Nightwing/etc. bundle packs. Those are completely worthless. No effort went into those! the only addition in them was Nightwing, and he doesn't even have a full move set.
My biggest fear is that Rock Steady is going to start nickel and diming for a lot of very small content in their next game.
