I've been playing DOOM 3 again (non-BFG) these last few days and began wondering what sorts of recommended mods and custom maps are out there for this game. I grabbed the Classic Doom 3 mod again (I had played it when it came out, long ago), but I am not familiar with any other custom content for Doom 3. I see a user here posted a map just recently. What else is there along those lines?
