Been playing Galactic War on normal difficulty, and haven't felt even remotely threatened after 7 matches. However it's not the enemy AI I've seen do stupid things. I haven't seen them do much of anything really. No, the problem lies in my sub-commander. Who: sometimes builds things like this for no reason: Sends a bunch of Hummingbirds over enemy bases and just lets them all die. AND builds enough bombers to snipe the other commander, and doesn't do anything with them. EVEN AFTER SENDING HUMMINGBIRDS TO DIE FOR NOTHING! I remember it being better than this, a lot better.
Play on higher difficulty... uber nerfed the lower level ai due to complaints of it being too difficult....
As i recall the bugs reloving around GW ai have not been adressed. And so the GW ai is essentially kaput. Try skirmishes.
Agreed - Get the Queller AI mod and play some skirmishes with the AI set to Uber Agressive, Uber Rush or Uber Tech. If you still find those too easy, give the AI an eco boost. I give the AI 1.3 eco and I only win about 1 of every 4 or 5 games. It's very easy to make the game as challenging as you want.
Play ranked ladder if you want to feel remotely threatened - the opposite players will make more logical mistakes too... Absurd AI is pretty difficult too
