Battle royale-like games

I was just curious about how easy or hard it is to make a new setting for games with alot of players (10 or more). Earlier, i was looking through the forums for stuff on Battle Royales, and i stumbled this topic. http://www.conquerclub.com/forum/viewtopic.php?p=80350&highlight=#80350
Apparently, Troy managed to make a 14 player game, which was removed "due to its illegal unauthorized status. "
I'm sure there are alot of people that would like to play in a game like that. and by the looks of it, Troy can make them. So how hard would it be to make it a setting?
