After seeing the trailer for A Machine for Pigs, the first thing I did was google "Amnesia Occulus Rift" and got this thread.
Adding my two cents, I may buy an Occulus for Hawken... but if any of the Amnesia games, current or upcoming, were to support the Rift... it would be a GUARANTEED buy for me. I'm hard to scare, and while I enjoy Penumbra, Amnesia, and their like because I'm a fan of creepy Lovecraftian horror... they don't really scare or unsettle me. I can imagine the Rift completely changing that.
I'm just saying, please support Occulus Rift - because Amnesia + Rift would be terrifying in the most awesome way.
