The stress for the gameserver doesn't matter, the missions are only few kb's anymore, most scripting and resource expansions etc are now inside the Mod
You can get the Mission Pack from 6thSense though, get's updated when I update more than ~10 missions.
Hmmm, im not so sure if I like all this pre-stuff.. I think the fun is that everything is dynamic and based upon ur opinion and feelings at the time of the briefing and not days beforehand, but I guess that's my personal feeling
Still, we cannot say how many ppl will be there at the evening so saying which missions we're going to play is a bit hard On the other hand we can aswell simply make up a list of missions that we will play when 10-15, ***16-20, 21-25, 26-30, 30+ players are there etc, but this still gives you a broad choice of possible missions
