There is a huge issue with the AI in the game. I did few testings and this is what I found.
in FFA 4 or 8 players as long as you don't start researching fllet operations and star increasing capital chip limit the AI will simply ignor you and will let you all the time you want to fully research all technologies.
In same game 4 FFA the AI will stop research after researching 18 tehnologies while in same period of time I managed to research over 56 technologies. It is needless to say that I steam roled all 3 AI with superior technology.
Next the AI isn't building any defensive structure and relays alot on low level units ie frigates and in rare occasions on crusiers.
I tryed all types of AI research offensive guard but it is always same thing. Personnaly I don't think it is normal to wipe out the floor with HARD Ai after just 5 games played.
Thank you.
