More abominations!
Interesting idea that reminds me of the player vs player mode (not vs) that was discussed way back. 5-player games where the 5th player act as a director. I think that there will be a lack of interest, unfortunately, for these light modifications.
But since I came to think of it, I’d like to promote the player as director idea again. Giving some maniac limited or unrestricted control of the spawns etc. would be like a supermasochistic twitch mode - i.e. good fun!
