Let me preface this with, I f***ing love B27. I forsee many sleepless nights of conquering the planet as Coalition.

Anyway, I've noticed that when I'm defending my site, I always end up attacking. When the enemy AI is basically finished sending troops, he just sits around and digs. And digs. Forever. On the desert map that has literally no gold, I waited ten minutes waiting for the enemy brain to quit digging and come at me. I was basically out of gold, and had a turret drone with no legs guarding my brain. Totally immobile and unable to root out the enemy brain, I spent my last ~110oz and bought a skeleton with a cheap gun and a drop crate. I managed to work my way to the brain, and very, very carefully... get slaughtered, and I was then forced to lose because the enemy brain would not leave my base, and I was fully capable of defending.

I mean, not really "lose" but it was impossible to continue, because neither me or the AI could/would (respectively) do anything to the others' brain.
Does anyone else experience this periodically? Or am I the only one?

If others do have this, my quick suggestion is a time limit on the AI's time to attack you, that resets every time he buys a unit.

Thoughts? Discuss?

It does seem that the gold dig AI tends to screw over the AI for campaign. I think it just has to be smoothed out.

I think the problem is not that the AI is not attacking, but it does not have enough gold.

I saw once the ai was trying to dig gold at the top of a cave, and jetpacks would not reach it. It got stuck in a cycle of jump, fail, jump, fail.

Through the B27 preview video Data noted about the possibility of an attacking AI brain that will call a drop ship to leave the site if it's funds run too short.

This would tie in well with future brain resources when you have no hope of winning an attack you could just pull out and rethink your strategy..
