Wow, I made a smarmy comment and you replied w/ and intelligent response.
What's happening to blues? Must be because this is yesterdays news
I'll throw in GLQuake as the killer app that sold many people on 3D acceleration.
EVE: Valkyrie is pretty goddamn awesome in VR. I would agree that it's a stretch to call it a "killer-app". I think the trouble for Oculus (and Valve, and everyone else). Is that no one really knows what the most compelling experiences in VR are/will be. Everything so far is just an evolution of an existing genre, but since (IMHO) VR is a more revolutionary platform it will almost certainly require a new genre to constitute a "killer-app". Current games are different in VR, not necessarily better.
Cockpit games are an exception, those are definitely better in VR - they're perfectly suited to the current constraints of the technology (player can't move around very much). It's fair to say though that if someone isn't in to cockpit games now, they're unlikely to get into them because of VR. FPS games like CoD... 'eh, not really that good in VR at the moment, because you *want* to be running around, but you can't, and that's a disappointing experience. Same w/ sports, RPG, and almost any other popular genre.
Myst, FF7, and Halo were all evolutions of previously successful concepts. So consumers could say "Hey, I like (Adventure/RPG/FPS) games, this new one is the better than all the others I've played so I'll buy this new fangled hardware"
I strongly agree that the touch controllers will be the key to a real killer app, because this new controller necessitates a completely new control scheme, which in turn enables/requires new genres (see: job simulator). Using existing controllers (xbox pad, kb+m) skews game designs towards the more "classic" game designs (ie: designs that are good on 2D displays, ex. FPS), but those "classic" designs aren't usually very good in VR - which makes sense - because they were created for traditional displays (over many decades)
I'll throw into that... it's very hard to developers to get their hands on these new touch controllers, and they can't really even begin to create these new games until they have them because the paradigms are so much different it's impossible to know what will work (ie: be fun) unless you can actually try it yourself (catch-22).
