Went out and bought this.  After Zitpopper showed me a few things playing coop demo the other day, I decided to break down and buy this.  After playing this all day yesterday, I will say I like it.  Normally I need some direction in my life but I spent the entire day randomly doing things.  Sure I killed some crime bosses but I did a lot more climbing and exploring.  As of right now, I recommend this game.  Check back in a month.  A buddy of mine is coming over today to check out the 360.  He is older than me and still a big time gamer.  His system of choice is the PS2.  I have been bragging about the 360.  His problem is that he lives in the country and has no access to high speed.
