Okay, so I go to check the Xbox 360 Backwards compatibility list seeing what game I can play on my 360, and it turns out that I can play Megaman Classic collection on the 360, but not X collection.
Not that I give a shit about X to go out of my way, but still it would be nice to have both collections added to my non-existent Xbox collection.
Though X collection is a waste anyway.
Get a PS2 or Gamcube/Wii, both have them but with better controllers.
360's controller is only good for FPS. Also Microsoft is always updating their backwards compatibility firmware so it'll be compatible in the future.
