ViruzzX is absolutley right in saying that the rift at the moment only supports pc because that's all it does at present if you decide to purchase one of the developer kits.
However oculus have stated that when they launch the consumer version of he rift it will support pc,Xbox and ps3
If it only supported pc they would be leaving a massive gap in the market for this product.
As for games well yes the game is going to have to be a game specialy designed for the rift
Which most if not all of the major gaming developers are doing just that right now and have been for some time now, many are working on re programming old games to work on it.
At present there is only one game rift compatible and that is Doom 3 and judging by the peoples reactions when they've tried it you just know its good
The game Hawken will be Oculus-ready and launches on 12.12.12!
If oculus keep there promise on launch of the rift it will work on whatever consule you use maybe not the wii maybe it will it really depends on the game developers to support it.
