Imagine a multiplayer game where two or more people are playing the same game simultaneously, and controlling the same character. I don’t mean controlling parts of the character, I mean the whole character (for example, if implemented in a first-person shooter, or RPG like Oblivion).
The game starts, and you are both playing the same character at the same point in time. The way this works is that each player is playing an instance of that character in the same world. Each player is able to make decisions and do things however they see fit with their character instance. The character that has the higest achievement score after a major decision or event becomes the save-point for the next period of play. So whoever makes the better decision, or who ever fights the best and delivers the most damage and kills the bad guy, win that round, and the game continues forward from that point.
This could be applied to games like Oblivion, where multiple people are playing the same character, and the one who kills the vampire, or the one who is able to pick the lock, wins that “encounter” receives a separately counted set of points (tied to the player, not the character), and the game is saved and continues from that point.
I think this would be a great game to play, you can jump in and out any time you want, and the game will continue to move forward because of the other players. Consider this idea GPL’d.
