I find it funny that that people dig at ms or underplay what they are doing with backwards compatibility. Ya this bundle is cool and their exclusives are great. But what ms are doing with bc should be applauded loudly. They r doing things for free that others would charge you for. It's truely 'for the player' move. Go look at knights of the old republic and oblivion upgrades... free.
