I can teach them about general economic and military strategy that they apparently forgot to program into the AI. Strategies such as don't bother upgrading buildings other than the colonial hospital and that there's no reason to terraform until your planet is already filled with level 1 buildings.
Also, that there's no reason to build mining starbases until well after the expansion phase is over.
The specialized military strategies are designed for crushing humans. For crushing AI, these special strategies are not needed. I crush them with raw economics and then destroy them with brute force.
Ignoring the not-so-implied insults directed at the devteam, have you sent in saved games to Frogboy to help refine the AI, as he has specifically asked for? At the very least seeing alternate ideas could be helpful to him as, last I heard at least, he is still working on making the AI better.
Still, I would take care that this doesn't turn into a "how to beat marigoldran [as he plays currently]" versus "how to defeat a human" situation. As I intimated in my last post, the two aren't necessariy the same thing. Making the AI better is something that Stardock strives for. Making it so it can be better versus one player's specific playstyle is, while interesting, perhaps not quite as vital.
In the end, I suppose it's up to Frogboy to decide whether or not your ideas for making the AI better are doable. Only one way to find out.
