I did think of using globals, but then thought it'd slow it down slightly. Might run a couple of speed tests on referencing Globals.* as opposed to a completely user-defined variable or a constant. Mind you, I think mine'd be pretty slow anyway...stupid single-thread Lua.
Also, holding back on mine lets me learn from the weaknesses of others', like stopping on a treeless asteriod, etc.
Anyways, a little tasteless of me to be talking about how my as-yet-unfinished AI may be here. I haven't downloaded this map yet, or many others recently. This one and Keep Your Acids look good from all the comments.
Finally, I thought that a map like Infected Empire would be a good AI battlefield since the map is symmetric and has thin chokepoint areas (the arms) and also a big free-for-all in the core. It can also be easily expanded for more AIs - simply add a new arm. Yes? No? Maybe? [/pascal sauvage, jumped up Frenchman]
