As someone who played Galciv 1 several years ago, let me just say that I'm very impressed with the improvements to the game. The ship designer, the new colony management, weapon types etc are fantastic. However, the AI still seems to need a little polish...
Playing on 'Tough' (AIs set to intelligent), I noticed via espionage that the Drengins had left their best planet - class 13 - almost totally undeveloped (at least half empty tiles). The neighbouring planet was also in a sorry state. No wonder I was light years ahead economically and technologically. What's going on here? Presumably it's a bug. Their other two planets were fine.
Also, while fighting the Drengins, I noticed they had a tendency to send out fighters from their planets as soon as they were built, rather than waiting a few turns to build a fleet. So I'd end up slaughtering a string of individual fighters.
The tactical AI in general seems a little better than GC1 (from what i remember). Still noticing some problems with unescorted transports - the Drengins moved them adjacent to my fleets a few times. Planets without fleet managers should probably create a fleet and intercept attackers rather than passively wait to be picked off one by one.
However, in praise of the AI, i noticed that the drengins systematically put together a decent fleet on my border, declared war, and followed up the fleet a few turns later with a transport. Sadly for them, I had been more or less waiting for it and was able to totally annihilate their military and take their captial within a few turns.
On an unrelated note...where are the 'Good alignment' armor improvements? they seem to have not been added to the game or to Brad's known issues list. The evil weapons are spiffy though.
Cheers
