First off:
Insert "Hi I'm new" schpiel here.
Insert adulations for IC and SD for making the game that I've wanted since I first bit into MOO2 when I still got up on saturday mornings for teh power rangers.
Insert adulations for forums for being "mostly" helpful
So I'm not usually the most vocal forum-goer, mostly chiming in here and there for any questions asked. Made this map, thought someone else might like it.
Basic premise:
Large system (350 planets), 10 players, 2 teams, one chokepoint. I thought about making it a single planet-to-planet chokepoint, then use the star as the chokepoint before deciding on a chokepoint "area".
Haven't play-tested thoroughly, so not sure if it's the greatest or worst map ever made, but I've tried to make it balanced. Not the prettiest thing around, but the lanes should match up correctly.
I usually only play singleplayer, but it should be multiplayer compatible (month long game?

). The teams are set for top 5 in the setup menu vs. the bottom 5. I reckon you could do less if you simply fill out the upper and bottom most spots first.
Feel free to tinker with it to your hearts desire.
