Question! by S.O.A.D.
A game where you play as a small handful of characters (in actuality the game follows their "souls" as they pass from one body as it dies to the next) whose lives are intertwined at every reincarnation. Something in gameplay like a cross between Indigo Prophesy and a Telltale Games game, where your actions at every reincarnation alter each soul. The character's traits, base opinions of the other characters, and all that fun stuff are tweaked based on your decisions. The conclusion could be vastly different based on your decisions. And there's no real "lose condition". If all your characters get dead, or really when they do, you move on to the next chapter of those soul's uhhh...lives I guess. You'd play as one character until you hit a point where you meet another, then you play the second up to that point, where interaction occurs. Then of course there's times where all three characters could meet as long as one didn't get ganked already.
I'd say you start with an American male during the gold rush, a Brave of one of the native tribes, and the son of a shopowner in a small town on the road west. This'd be in the 1840s-50s
Then they're a Brit during WWI, a French nurse perhaps, and an officer of the German Empire.
Then an American GI circa WWII, a French nurse Belgian father, and a wounded Nazi.
A pair of French soldiers at Dien Bien Phu and a Vietnamese sniper.
An American spy and two Soviet "interrogators".
Obviously you'd have the choice to kill or not kill people at moments where you meet yourself I guess is how you'd put it since you play all the characters and that would subtly alter the disposition the reincarnations have of one another. I'm crapping myself about how good of a game this could actually be. I might start making notes for serious. I spent way too much time on this when I should be sleeping, which is probably why I've run with it so hard.
