It seemed like a hilarious addition to the list. While still being somewhat reasonable. It was that or Robot Roller-Derby Disco Dodgeball.
I'd recommend Factorio as an *awesome* building game. It's not the same kind of long-lived total community thing as an skcraft minecraft server, though. Multiplayer is a feature, but it's pure co-op (no competitive features) and the progression hits the end in about 12hrs of play; it's also more purely planning and less the kind of aesthetic self-challenge possible in minecraft.
I've been thinking about taking https://github.com/thinkofdeath/steven , forking out all the usable bits of voxel/render code, and running with it to make a new game styled after our favored brands of industrial MC, but designed from the start to include competitive aspects and team mechanics. (...and at least a few mechanics that face the economic singularity issues head on with similarly scaled challenges, environmental or otherwise; in some situations this might mean leaving behind the linear costs always dictated by minecraft-style crafting.) But, I need Yet Another coding project like I need a hole in my head, so.
I don't know if anyone has tried it, but there is a game called 7 days to die on steam. You can do a custom server and it is multiplayer. It's pretty much a more detailed minecraft. But I do enjoy playing it with my friends when we all have free time.
