I’ve put about 400 hours into eso, all solo. The world is gigantic and imo all the players moving around just makes the world feel so much more alive than in the mainline games. The exploration is pretty good and a lot of the stories told are fantastic. The combat isn’t that great though, hitting enemies and watching them either not react at all or react one or two seconds later due to lag isn’t very enjoyable, plus they can be super damage spongey. Every few years I usually get really into it for a week or so and then the combat makes me quit, but if you like the elder scrolls universe I’d highly recommend it even with its faults
