I have recently bought Jump, End Space, Fusion Wars and Wands.
Jump is great. A bit sparse but the jumping mechanic is solid. You do feel a bit like a super hero.
End Space is amazing.
Fusion Wars is good fun. The sliding mechanic takes a bit of getting used to. Single player may be a bit limited, I have yet to try coop
I haven't tried Wands yet but its meant to be good.
I also hooked up with a few of the rifters (hai @Fox @Sponge @Strategos ) to try Alt Space and it worked great. They obviously had more fun being able to flip me the bird with their fancy hand presence but was still a great laugh.
I am getting some overheating so have also taken to strapping a gel ice pack to the front of the headset. its not a good look!
