Man, I do miss MCP's Universe Builds. The first few were just flat-out some of the most spectacular builds seen in BL even today.
I miss when I was running 2-3 servers simultaneously too, and when people would think I was just doing the ol' "fake server" trick. Until they joined. Those were always fun because I'd screw with my maps - put in a different sky, add antigrav or bounce zones, add hidden areas waaaaaaay high up or down below.
