i have 0 programming experience in this stuff so all i can do is suggest, although i do own multiple dedicated machines in several different data centers around, but thats beside the point...
how about a game play addon that mixes 2 popular game types, gungame & some type of the zombie mod... if this has already been mentioned excuse my stupidity as i just joined the forums but if it has yet to be said how hard would said game type be to program? is it even possible?
