I was wondering if this is a universal thing - everytime I start a local game, the cuts scene of the Turtles jumping down to April's apartment building always gets cut short. I've even set the controller down to make sure I didnt push any buttons, but it still happens. It's not a big deal.... but still a minor annoyance. I like the cutscenes.
Yeah, the cutscenes are a little messed up. If you're playing an on-line game, you'll see the full opening scene. On the other hand, if you're playing an on-line game you'll never see the ending. Once you leave the Technodrome you just see a quick 'game over' message and go back into the lobby.
Likewise, I've only ever seen the "Oh no, it's that overgrown cork-screw again" line (Stage 4) in an on-line game. Or maybe you need to have 3+ players to see that line?
