So I finally finished my first game of AI war. I was playing a 6/6 with hard golems and a few other minor options on and I enjoyed the game quite a bit. It did however feel a little easy. I felt like I was chewing through AI planets one after another with very little resistance. I went for a medium/low AIP strategy and was attacking the second AI planet with something like 400 AIP.
For my next game I went to 7/7 and added fallen spire and I found the jump in difficulty to be rather jarring. I wonder why there is no difficulty levels between 6 and 7 where it seems like many players would fall? Then again maybe some of the problem came from fallen spire I'm guessing the AI response is not affected by your AIP since I only had 4 planets when retrieving the shard for the colony ship and was assaulted by hundreds upon hundreds of class IV and V ships which left me in such a weakened state the next wave took me out.
Golems are awesome but the Hard level still seems to be not enough of a tradeoff for such power (although maybe it would be different if I was on 7/7). Whereas I found spirecraft ships to be a little underwhelming in comparison.
Overall amazing game and I'm really enjoying it!
