RPG + OR + possibly ARAIG = bliss.
Aren't Oculus Rift and ARAIG mainly made for games designed in first person though?
Skyrim looked like it could be pretty neat played that way.
Yes and yes. This isn't going to work for a tactical squad game very well other than moving to zoom around the battle field... but for a first person RPG this is the future I've dreamed of. Smaller squad based could use OR very well to just make you feel more like you're *in* the game, you'd only use/need Omni for the first person... but think of the glory. Skyrim, Gothic, Deus Ex, System Shock, Vampire the Masquerade, Thief, Fallout, Borderlands, Mass Effect, Bioshock.... there are a ton of FP POV games this would be amazing with.
*edit* And for games that are 3rd person or top down... this might actually make first person viable. I'd be highly interested in a Diablo/Path of Exile that could do first person with this combo... constant turning and scanning because demons could pop up anywhere could turn ARPG into something more pants shitting.
