Just thought I'd bring to your attention that some of the guys from Monolith (F.E.A.R.) built a FPS on the UDK which means you can run it on Vireio as an Unreal 3 engine game. It's pretty intense. Here's some screenies from steam:
Nice, thanks for the suggestion. We are hoping to have a more formal way of requesting game support in the future (as well as showing what we are working on, and also what has already been requested). This one was already on my steam wishlist... once it comes down in price I'll give it a go and try to add a VR boost profile (custom FOV / better headtracking / gamepad support).
