The standard troupe of VR games, job sim, brookhaven experiment, the games I listed previously, the climb (great fun but again, feels more like a tech demo than a game). Echo arena was something I got to try at E3 actually, hadn't played it before. Novel movement tech, something that also needs to be improved upon but echo arena fixes it in a novel way (though I doubt it would work for every game). Onward and pavlov I didn't have a chance to try, but looking at them now, they look like pretty generic FPS games of which there are a slew. I don't see how they'd address the "gets repetitive after a few hours" complaint I have, especially considering if I wanted to play an FPS with my vision gimped I could just put blinders or tape on the screen. But that's just me. Competitive stuff isn't ready for VR yet, period. RIGS is a prime example of an attempt and massive failure.
gunheart looks like a kind of kitchy tower of guns styled game with the weapon variety, and I can dig that. from other suns looks so early in beta that I wouldn't want to form an opinion on it.
There's just not enough unique stuff. Obviously VR will lend itself extremely well to FPS and walking sims. But I want to see people try to do more.
