Yeah DOOM definitely has a large community too, maybe even a larger one than Quake. Kind interesting how some games enjoy large communities while others do not. e.g. Blood and Duke Nukem 3d are both very good games but their communities are smaller.

I think in this particular case the cause it pretty obvious. For Doom you have Ultimate Doom Builder and Doom Tools. For Quake you have Trenchbroom. For blood and duke nukem, you don't.

They do have a modern version of mapeitor but yeah it's probably not as good as the other two, especially Trenchbroom.
