This topic has been passed around quite a bit because I believe it's something a lot of us would like to see.
This might sound strange, but I would like to see a game based on Letters from Whitechaple. For those unfamiliar, this is a game where one player plays a criminal who must run from the other player who is trying to catch them.
This would be perfect for the Rebels playing the runners, and the Imperials trying to interdict them. At the start of each round the rebels choose a mission and the planet it starts on, complete it, and then make a run for thier safehaven. It can all be abstracted out so the game can be played alone, or include missions so that you can fight ground missions with Imperial Assault, Fighter Raids with X-Wing, of full fleet engagemants with Armada. It could have a full campaign built it so both sides get more powerful as the game goes on.
Instead of a board it could have tiles so that each game could be unique.
I really want to play this game.
