[PROTOTYPE] is actually a good game, but once you beat it and get all the upgrades and stuff, it gets very boring as the events are almost impossible to get platinum rank on.
COD: WAW has a decent campaign, but the online matchmaking sucks because almost everybody online is a noob by using MP40 Juggernaut.
Assassin's Creed was a pretty good game with it's secrets and decent length storyline. The only bad thing is that once you beat it, your going to sell it or throw it away as it gets dull.
Banjo Kazooie Nuts and Bolts kinda sucks because it is nothing like the older games which were fun. I must admit though as it is very customizable.
