What current XBox 360 games do you own and which ones kick some major ass?!

Right now, I own Perfect Dark Zero and Need For Speed: Most Wanted.

Perfect Dark Zero is a good game...great Mission mode (Campaign - Story mode) but I feel that the multi-player is lacking. Perhaps more time with it will help me believe more in the multi-player aspect of the game...

However, I can assure ALL of you that Need For Speed: Most Wanted kicks some major ASS!!! If you even remotely a fan of racing games, this game is an absolute MUST HAVE! Seriously, I haven't enjoyed a racing game like this.....ever! Right now, I'm playing the Story mode and am doing well. I have probably put in about 10 hours so far and I'm about 20% finished with the story mode (I'm not exactly sure, but, that's about right). Every moment of this game I have had has been so much damn fun...

How about you guys? Which XBox 360 games do you own and....do they kick some major ass?!
