I have seen those sort's of deals and really skeptical, I feel like you would buy it and they would reset the password somehow and steal the account back.
I played a bit more yesterday and I think it was growing on me more and more, as you say it scratches an itch but I'm not entirely sure what itch that is 😄 It's not perfect by any means but it's big, there appears to be quite a bit to do and explore and you have to just keep in mind that the game is initially a sandbox to play in and then the story is a secondary feature. I suppose a bit like how Fallout 76 turned out and how Outward is meant to be I think?
