This is completely off the wall, and probably not practical, but I still think it would be fun. What if you were to introduce some sort of themed time slots. The themes could be something like:
- Monday, Wednesday and Friday from 8-9:30 all knife areana maps
Tuesday and Thursday 7 - 10 sniper maps
Saturdays from 8 - noon smgs only
I realize that this would probably require additional changes to the deadm mod, but I still think it would be fun.
Another thing that would be cool is to add areana modes where players all start with the same weapon, and aren't allowed to buy different weapons. Possibly even the special weapons, although I don't relish the idea of Napalm arena. I don't think that one would last very long. For some reason I seem to remeber something like this on the server a long time ago, around the time the special weapons were introduced, but I might be mistaken.
