I just finished Area X in Rez. OMG, I want a full Rez 2 like that!
I'm not too impressed with Harmonix Music VR so far. There's the psychedelic caleidoscope visualizer, the dull island visualizer, the simplistic "pose a doll" dance thing, and then the modelling that I can't try yet without two Moves. Is that what everyone is raving about?
Thumper is cool but a bit too strict on the timing for me.
Those are the games I bought so far. From the rest, Battlezone was nice and might be worth buying. Rigs was not my thing. EVE was over before I could blink. Driveclub is sort of cool. Allumette was neat but VERY brief. VR Worlds is mostly just good for the diving demo, which was my first introduction. I'm looking forward to trying the Playroom games though, they seem to have a Nintendoland vibe. And that platformer was AWESOME, I want more!
