Not played Robinson yet, but I think in these salad days of PSVR it still holds some value just by showing us the most gorgeously crafted VR environment so far [reportedly]. I'm getting it myself soon, in with a bunch of other Christmas shiz at a knock-down price and without having to pay up for a year, so I'm not likely to be as offended by its shallowness as a game as someone who's gone and impulsively thrown £50 at it, in anticipation of playing the first PSVR "killer app". Just the promise of exploring a vast jungle landscape populated by dinosaurs is enough for me to have a nibble; I crave something Jurassic Parky.
It's a shame Naughty Dog are done with Uncharted now, because that'd be a wondrous exotic cinema trip in VR - wandering through wildernesses searching for artifacts, climbing like a monkey, matinee car chases... you name it, you can toss it all in there and it'd fit pretty snugly. Might feel a bit weird to start with in first-person and adventuring alongside Drake rather than as him, but I'd dig that change-up myself.
Perhaps with Uncharted's retirement, it's a perfect time for Indy himself to make a videogame comeback - without VR it probably wouldn't really be worth it, but I can just see so many possibilities for that sort of filmic rollicking archaeological globetrotting romp.
So far, the best visual applications on PSVR are sort of separate from the best gaming applications. Those class games obviously do their own graphical thing brilliantly efficiently (I love the economical atmospheric look of Thumper, for instance), but moments of absolute jaw-dropping beauty are mainly from the more 'VR experience'-type showcases, which don't really offer so much in terms of revisited gameplay. That killer app I feel will be the first one that nails the sheer cinematic transcendence of this medium but seamlessly combines it with compelling in-game tasks, with added polish to seal the deal. It'll come.
