Criterion for the AI getting a Core Forcefield?

[RCIX]

I am playing another game (this is quite possibly the first one that i really 'get' by the way ), and on a MkI planet next to my homeworld the AI has reinforced with a Core forcefield and an MkIII FF around their command station. It's not too big a deal for me to crack, having maxed out bombers mki-3 + fighters and laser gatlings, but i was wondering why did the AI choose to do put a core FF there? Because i'm somewhat sure that it wasn't there from the start (it might have been though).

Can't the AI buy a core forcefield from the trader? I remember seeing that on the list of things the AI can buy from it

It is indeed! does the AI have any preferences for buying stuff at certain locations then, or does it just have a small chance of buying something random whenever the Trader enters another AI planet?

The second thing -- small chance of getting something random. The worse stuff, like ion cannons, are more common. Glad this game is going so well for you, rcix!

Thanks i picked up a ZPG with my first planet acquisition so it's been a bit more smooth sailing than usual!

And that's sneaky; i hope the AI doesn't pick up an Ion cannon for that planet
