According to the developers, it’s “Ultima Online meets Gary’s Mod.”
This is ReWorld, an upcoming multiplayer game that uses procesurally generated worlds that players can modify and shape with the eventual goal to share with other players. Basically, if you’ve ever had the inclination to build World of MassivelyOP or somesuch, this is the game for you.
“Once your world is created, you can still modify the original game by adding races, classes, house designs, events or any other system you want to differentiate yourself from other worlds,” the team said.
ReWorld will eventually be a free-to-play title, but currently the only way into it is to pay into the founder’s program. It has a pleasantly light cel-shaded aesthetic, and the team reports that the combat and dungeon system has made it into the game.
