Stumbled upon an interesting map idea on Reddit
This sounds similar to a UMS map I used to play in Broodwar called 'Phantom'. You start with 8 players all of whom are allies (usually on BGH) and one of them is secretly chosen to be the Phantom. The Phantom recieves unlimited resources and is tasked with killing all other players. The other players must find and destroy the Phantom. The game usually progresses with the Phantom remaining hidden and attempting to disguise any build up of troops or production facilities. The other players want to expand to gain strength to fight the phantom but limited resources bring them into conflict over expansions. I'm sure you can imagine all the fantastic mindgames that can ensue from this and it definietly adds a new twist to playing RTS games!
However, the problem with this setup is that the quality of the game revolves entirely around how good the phantom is. I've had amazing games where everyone has been so pananoid and just tear each other apart before the Phantom is finally revealed to be that sneaky guy in the corner (who was so weak you thought he could never be the phantom) and he then crushes everyones weakend forces! You could also have rubbish games where the Phantom is immediately revealed and then can't compete with 7 enemies and gets crushed himself.
Do you think something like that could work in KaM?
