I thought the gameplay was great (still do), and the AI I had no issues with, in fact sometimes they'd do extraordinary things. There were some hilarious glitches like dudes flying a mile up in the air from explosions. There are some great inspired levels too and i cant wait to see what they come up with next. What they need to fix is the crap presentation, the game has no replayability because you can't just go straight into the action from the menu, you have to watch cutscenes all the time. Multiplayer was quite good too.
I'm happy enough that RS2 is confirmed to exist.
