This is a great game and is deffentily worth owning an xbox 360. Single player mode is pretty great. The story line is amazing and the side missions are tons of fun, there is easily 150+ hours of game play. However, that being said multiplayer and co-op is a broken feature with this game. The fact that you cannot import your own character into the game with your friends and that you must use a pre made character with your skills and abilties is an instant turn off. Also, your weapons are not the same as your original character. There is also the lag issues and the co-op issues interacting with the games AI is nothing shy of horrendous. The fact that you can make 20, 000 gold in the first half an hour of gameplay makes the game far to easy. Bottom line is this is a buyer but if online is your thing your needs will be better met with WoW. :P. But if you're satisfied with offline gaming, be prepared to be playing forever as it is really addictive.
