You guys just have to give the game a chance. Start going for the in game trophies and you'll start to like that kazoo sound that happens when you unlock one! Oh yeah, I've had 100% in this game since September '08 and I've 100%'d all the DLC that came out since then. I'm part of a clan that has about 10 members on playfire.com and we all have 100% so it's def doable.
Impressive plat well done, I have the game but don't have the patience for it
