I could even join it, which isn't possible if you start a mp server. So I launched the game and played against myself. Switching to the other side easy to do by just alt-tabbing to the other game. I did this with a 4-player game with 4xMultiwinia running simultaneously. Here's a screen when the game ended.

I won the game of course
The game lagged a lot though, but I run 4 instances of the same game and the small island on the screen shows at least 1500 multiwinians. Elsewhere on the map there were lots too. But it was still fun, funny was that the red Vinnie_NL got a crate near his spawn point, I wasn't controlling the red at that time but they captured the crate anyway. It turned out to be a randomizer which affected all multiwinians near the red's spawn. This resulted in a fight which red lost so red was eliminated from the game by a simple randomizer activated at a spawn
This can be very handy if you want to try and experiment with stuff, if your system can handle it. While I was doing this I noticed one cpu core was maxed to 100% and the other one to only 30%. So if you can assign the second core to the second game instance it runs better I think. But I haven't tested it yet. And if you have a quadcore cpu you can have 4 games have their own core
