So far you did a very good job. I especially like the terrain and map and the build-up animations of the buildings. Are you planning to add any sentry towers or guard towers btw? Or perhaps wall structures? Anyways, keep up the good work, as I'm experiencing myself at the moment how difficult AI programming can be.

Another question by the way, you use a node system for pathfinding, right? (in your latest version too?) You simply put 'beacons' around structures, so they won't run into them, or do you store all possible routes into a txt file? My own pathfinding works perfect with levelblocks, using scans and checking the content, but this doesn't work with model-only levels ...

Cheers
