Spending the big bucks on Xbox 360 games

Playing on a very costly and sweet gaming setup (minus the television) velodyne_76 has invested a lot of time and money into his video game hobby addiction. With over 150 original Xbox games and his Xbox 360 library growing past 116 titles, we can't help but wonder if there are even 116 Xbox 360 games that are worth purchasing. Actually, we just noticed a copy of Pimp My Ride in his game collection, so that answers that. Not a problem though, because velodyne _76 is rocking out to Guitar Hero II, watching HD content on his HD DVD player, and playing A+ titles like Gears of War. So fanboys, can anyone one-up velodyne_76 with either their video game collection or gaming setup? Just cash out your life savings and go on a shopping spree, it'll be fun.
