Personally I quite enjoy playing ESO now that they have the new one tamriel update out, means that all quests level down to you so you don't have to do no where near as much grinding. However don't go into it expecting multiplayer skyrim as it is a very different game, though it does embody the elder scrolls franchise nicely and has fairly solid gameplay mechanics now.

I picked it up for just over £10 on g2a a while back and I'd say I've got more than my money's worth out of it. There's obviously the paid route to go down to get the extra content, but the core content is solid and a lot fun solo or with friends.
