Currently i'm playing on a large map, abudant habital planets, stars etc. with 5 computerplayers. I've build lasers first, then went al the way to photon torpedos. The computers however still counter my lasers but not my missles. Which of course is a good thing as i'm ripping them apart. The Ai ships all got lasers (plasma weapons etc.) so I use shields. My ships are nearly indestructable as a result. Mostly I combine weapons (8 laser 10 missle so forth). This tactic seems to work well.
Question is will the AI pick up on this. Will they combine weapons and/or defences? If not war is going to be very easy i guess.
