A pal of mine and I got a bit into TS, so I decided to try and build a map that suits our kind of slow playstyle and love for chokepoint defenses.
This map was built with two human players on the northern and southern position (1 and 2) and a hard AI in the middle (3) in an all-vs-all situation in mind. Of course you can always cut out the middleman and leave out the AI, or let a human try to hold the middle against two enemies.
If someone should play it, I'd appreciate feedback. This was, after editing one existing map, my first try from scratch and I'm thinking about doing another one or expanding this one.
Hopefully have fun!
