Today there are not many games for Oculus Rift. This is mainly due to the fact that the device is not yet officially released, and most of the projects are still in the process of development. However, first solutions are already appearing.
Shane O’Brien has created an environment of Game Boy for Oculus Rift. He used Unity engine, which contains an emulator of the portable game console.
If you own Oculus Rift, you can find many different experiments and small developments.
