Deadliest Catch has to be the worst game to be released in the past couple years... I've only seen it played, and I already know I wouldn't take it if someone dropped it on my doorstep.
There is a 360 game called Chromehounds that was pretty terrible. I spent about 20-30 minutes trying to start the training because I couldn't figure out how. It was the only game I've ever taken back actually.
Mw2... But if IW decides to fix the stuff in the game and make the price of map packs $10, it'll be better. ET is pretty bad. I have it, on the Atari, and I played it twice and wanted to kill myself
