I just started the game, and I really like it. I especially like the vast world, which just invites exploration. However, I think exploring would be more fun if the map were blank at first, and filled in each location as you arrived there. That way, players would really feel like they were discovering new areas.
If people don't like that, then at least mark which locations a player has and hasn't been to. It would make it much easier to gather exploration XP.
I really like this game, and I'm excited to see it go live!
