For folks into things like Skyrim, Elder Scrolls Online runs beautifully under Steam Proton, is currently free to play for a few days, and also on a cheap deal (£6 for the base game/Morrowind).
There are a few minor MMO things that distract from playing it like a classic elder scrolls game but not much, and all the subscription deals and other stuff really is only relevant to end game, player-v-player stuff and group things.
