I don't really want to rewatch the 4 hour or so stream but off the top of my head' -ship combat wasn't fun (he didn't get it and found it unreasonably hard) -he did not care for the RPG elements and doesn't like games where you have to play for a lot of hours before it becomes fun -he found the combat clunky compared to other shooter games

He admitted he probably wasn't the right audience for the game since he never really liked Bethesda games. He just wanted to try something different. Also story seems to be not that important to him generally. I personally love Bethesda games and can get completely absorbed in them. But I can also definitely understand it's not for everyone.
