Someone mentioned custom gamemodes, and I think that would be great! It would be a very nice rally to scrap.tf, as it basically advertises the website to the players. Muselk's Zombie gamemode, as Ezekiel mentioned earlier, is a fun one, but unfortunately, only M Garden (Muselk) servers run that, and they're pretty much always full. I'd love something other than TF2Ware and x10 randomizer. Something new and interesting.
