I imagine this sort of games more on a Augmented or Mixed reality platforms, but still if well developed they could turn it into fun VR game/s also.
Yesterday I was thinking exactly what game would I want to see adapted/ported or build from the ground up... Some stealth (Splinter Cell wise) game. As shooters are already in... I was thinking Splinter Cell like game with "less kills the better" some cool gadgets. Would be awesome!
Co-op missions with a friend/s ? I think it could be a lot of fun.
