1. No instruction manual, go online to view it. Boooooooooooo. I actually like looking through it. Cheap. Cheap. Cheap.

2. Exclusive playable character: Catwoman. Yeah, buy this game new and you get this. Buy this game used. Sorry, outta luck. Again, boooooooooooo. Not only is it a hassle for new purchasers to add in these codes, this hurts the people who don't have the money to spend $60 on a game. I know companies hate the used game industry, but this only promotes more piracy. If they're worried about it so much, maybe lower game prices to $50? Hah! That'll never happen.
However, there are reports that Gamestop is giving out free Catwoman codes with used games. Maybe we'll see more of that in the future.
