How's ESO as a single player game? I keep hearing it's very worth it for the great and non-fetch quests, a friend even used to say it's the best Elder Scrolls game when it comes to quests. I don't wanna add yet another MMO to my library tho (theoretically I "still play" FFXIV and GW2, though I haven't log in them for a few months now) so essentially I'd like to treat it as a single player TES if possible.
It is an excellent Elder Scrolls game if you enjoy questing and lore. I have an ungodly amount of hours in Elder Scrolls games starting with Daggerfall. It took me a while to get warmed up to ESO. That was when I treated it like an MMO. I started to appreciate the game when I began to treat it like a single player game, taking my time doing each expansion (dlc, chapter etc) in chronological order. The ESO team really does a good job with the quests and lore. If you do decide to play, just let me know if you have any questions.
On a sidenote, as I know you don't like pozzed shit, the game does have some faggotry. But for the most part, it stays in the background. Elder Scrolls lore is pretty whacky pre Oblivion and Skyrim. This game treats the lore how it was from Morrowind as well, so it gets pretty strange at times.
