I don't play video games often nowadays, but when I do it's usually driving simulation games like Euro Truck Simulator 2, American Truck Simulator, OMSI 1 or 2, openBVE, Microsoft Train Simulator, etc. Those are generally relaxing for me. I sometimes explore a little on OpenSimulator now too. I used to play Minecraft and Minetest with a whole bunch of mods with some friends, but I'm no longer interested in sinking so much time into building a world that gets erased this easily, I would rather create something longer lasting.
