Ashes of Creation is another sort-of sandbox-ey MMO with trade, economy and town building plus dungeons, raids, etc. This one looks a little more high fantasy. It also looks a little further along based on the Twitch streams they've done with their developers. They should have a playable alpha (which you can buy into) this year. I've been really looking forward to this one and happy to see they don't seem to be rushing it.
