Going back to the original topic, I was thinking about AC:Brotherhood. But if it doesn't challenge you to be stealthy as possible then its a bit pointless.
Another one...COD: Black Ops. I don't want to buy it and find it has a pathetic 5 hour campaign and plays exactly the same as Modern Warfare 2. Although, the latter part isn't necessarily bad thing since since it was pretty epic, lol. Not really, it is a good game though.
Naruto Shippuden: Ultimate Ninja Storm 2...bit of a mouth full. Ive heard both good and bad reviews. But I think the fanboys are giving the good reviews so I'm not sure.
