I agree with blu that the cartoon server can get boring. The family guy map is certainly lacking in complexity, and usually turns into a game composed entirely of firefights on a completely open field. The simpsons map i like a lot. I think we should keep the maps, but possibly add a few into the rotation. I also noticed that the maps are labeled as betas, so maybe a future update will yield a better FG map.
As for the obby server, I like the mod a lot, but it wasn't popular enough at all. There are plenty of Obscurity servers that are way more popular that people are going to go to before they even think of ours. I would suggest including the obby mod with our favorite maps into a mod rotation server. As kat mentioned earlier, there is a really good zombie mod out.
Pwnsauce has also found a great deal of addon maps that we could potentialy incorporate into a server. It would be nice to spend some time testing out certain mods and maps on a specific server that hardly gets any traffic, of which we currently have 3 (s2, 3, and 4).
For a mod rotation server, I understand that people may not have had enough of a certain mod, and do not wish to be switching in between drastically different types of gameplay so often. Including the ability to vote to skip certain mods or maps may solve this issue. This way we could potentially have a server that allows the users to keep it running 1 out of however many mods the server runs for as long as they like.
