Electronauts is worth $5. It's not a game, but a sort of electronic music soundboard thing.

Space junkies is also worth $5 but only if you have some friends to play it with. Has a bunch of fun weapons and zero-g movement, but hampered by dead development and shitty ubisoft client.

The Talos Principle is part of the Croteam VR bundle, but it's actually a pretty good puzzle game. might be worth getting by itself if you like puzzlers but don't care about serious sam.
