Do it! I just made the switch (using PopOS as my distro, AMD CPU, 1080ti GPU) and haven’t had much trouble with my extensive Steam collection. The biggest issue so far was Bioshock Infinite which actually runs native and I had to edit some configs for texture pools. SteamVR / Index has been a little unstable but seems to generally work (I don’t use it enough to be sure if it’s Linux or my hardware getting old).

SteamDB has been a excellent resource for checking compatibility and game specific tweaks.

I’ve heard of Boom Aerospace from the US, which is a little further along in their development process, although they are only super sonic.

It Takes Two! I played it with my partner and really enjoyed the story and very imaginative game play.
