There are plenty of similar generators, it's not very difficult work.<p>What I'm more interested is making this a 3D world with procedural geometry, make cities, make it run as a multiplayer game... Not to mention you cannot store all that geometry, it's too large, you can only generate the place you're exploring on the fly and save it to a cache and then render it.<p>Then you would have to explain all your artists and game designers how to make all of this work. It's a lot of constraints. The multiplayer side won't be interesting unless the world is persistent, so you have to split the world into several servers to not overload servers, because players need to cross the path of other players for the game to feel alive.<p>AND THEN, you would have to adapt netcode strategies in very densely played areas like cities where you have a lot of players next to each other.<p>In the end, such game would be very popular, but I don't think you would need a map generator like this, the map would still be done by a human because it would yield better results. What matters is the high resolution procedural geometry, at a low scale: trees, terrain, buildings, etc.<p>So yes, that's essentially the story of developing world of warcraft, except world of warcraft has several world instances and phases, because their world is not very large when you look how many players they have, they can't have a single world, even when they use phases, which is not a cool feature.
