playing game console way

Hi! Me and my pals are working on a game in unity3d. We plan to relese it on Ubuntu,but...

We want to run it like would be on a game console, just put CD or other flash drive and it will autostart. How to do such thing? Making game portable and add to CD autostart app is good option or is there simpler way?

We came up with this idea mixing SteamOS and Ouya- simple playing good games on linux game console
