I think it'd be neat if the game didn't end when I lost but quickly played out the game until one of the AI players (or all or whatever) won. Would be cool to see who ends up on top, especially after surrendering to a given player.
For example. In my last game I was doing well despite being gangbanged by every single opponent except the Drath. I took out everyone but the Terrans, the Drath, and the Krynn. I got the Terrans and Krynn off my back but the Drath were far too powerful from being left alone for so long. The Terrans then attacked again so I surrendered myself and all my goodies to the Krynn. I would've liked to see how that game would have played out, since the Krynn and the Terrans were rather close friends and they probably would have teamed up on the Drath.
