I got this a few days after release.
It a fantasy, Viking, survival, RPG type game.
A very tiny install, as all the graphics are procedurally generated.
Runs pretty well, is a bit buggy/laggy occasionally.
Hasn't crashed for me yet, but did for my son who plays it a lot.
OK with that anyway atm, as it's still early access.
Quite fun and has a really nice fantasy sort of surreal ambience to it.
I built a 24/7 Valheim server on a spare mini PC with a server manager over it to to restart with crashes, scheduled restarts and other features too. So it's pretty low maintenance.
Anyone playing it?
