Clover
I call it Clover.
It's a simple three-way map, one player in each section, should be fairly balanced and is also pretty small. I've made mission files for both single player and multiplayer. I haven't yet tested the multiplayer mode but I see no reason why it wouldn't work.
As for single player... the AI are poor and I've had to give them extra resources to compensate... but I may also need to give them some starting troops if they're ever gonna stand a chance. But it works anyway.
So... what do you think?
