Polybius, Conductor and Rainbow Reactor have decent reviews, I may get them.
Raw Data was also quite popular a few years ago, but I haven’t heard it mentioned much since, so I’m not sure about it.
Cosmis Trip is decent fun, but not for that long, and I already have it. It’s fine though.
As for Grip, I’m pretty sure I own it… Somewhere. I’ll have to try it in VR, didn’t know that was an option.
