I've purchased this game based on the reports that the AI was quite good and have updated it to 1.4x
I'm playing on Intelligent and while I've only played 4-5 games I am a little disappointed in some of the AI decisions...
AI seems to build starbases in locations that don't benefit it, eg ecomomy in far flung corners of the galaxy away from their planets - no trade routes. Military starbases appear to give my ships a massive advantage once you apply a few bonuses(which is fine) but the AI sends in wave after wave of ships to engage my ships within it's sphere of influence rather then avoiding the thing. This wouldn't be so bad if the AI employed a similar tactic but it hardly seems to upgrade any of it's starbases to levels that would cause you to avoid them, or make them a critical target. Unprotected troop carriers seem to park themselves next to my ships for target practice...maybe I was expecting a bit too much but victories seem a little hollow when these thing happen.
(on a positive note the AI did take out a fairly beefed up starbase with a large fleet. Although I had assumed that it would be safe as it had a few ships parked their that didn;t get involved.)
Is there some mod out there that can address this stuff? I'll pump up the difficulty but from what I've read in the manual this won't give them better tactics
