No one has use for 300 new maps LOL
I guess you are not mir positive, likely didn't play official mir servers. You just see what's available here and try to make others to do things with it to your liking, along the lines of some other games out there that use(d) auto generated maps.
Why don't you try to make at least one map in map editor, otherwise you are like a kid who wants to sprint before he learned how to walk.
BTW what's this MS stuff, are you maybe their game developer trying to steal know how over here?
