Planet Xbox 360 has a list of games that won’t play on the Xbox 360, and it looks quite long. Joystiq points out that it has some inaccuracies, but it’s still a pretty good indication nonetheless. What they did is take the list of all Xbox games, subtract the compatible ones, and got this list of incompatible ones. Of course Microsoft will be working to shorten this list, but it gives you an idea about what you’ll be missing out on with the Xbox 360.
