SupCom, set to hard. Using the strategy of rushing very early with a bunch of bombers. what happens? the AI build way more factories than should be possible and upgrades everything to at least tech level2 within 10 minutes. My engineers are busy at work building point defense guns and anti aircraft guns, a rush of T-3 seigebots and my defenses are useless, all offensefive units gone, my base is being attacked. 20 minutes into the game, one tech 2 engineer left, he's building a point defense gun to finish off what i think is the last t-3 seigebot in a wave, he's destroyed and my two shield generaors are failing because of constant attack by a t-3 strategic bomber. one failing factory left. one nearly dead shield generator left. 25 minutes into game i end it because it is very hopeless.
point is... AIs cheat and build way faster than they are supposed to.

they also did a very good job of making sure i had no access to resources to build.
