Yes, this following scale with AI difficulty in this submod:
- AI contrast, that is the difference in AI combat power between the AI's attack force and whatever it is attacking will be bigger on higher difficulties, and attack fleets will be larger.
- AI response time, which is the forced time delay between AI decisions and actions is longer at lower difficulties (both in space combat and GC)
- AI credit income bonus

AI unit HP, shield power and damage can be adjusted with difficulty levels as well along with unit build time in GC - but none of those are active in this submod (they have the same values as the player does).

I just dont know. Maybe I'am suddenly became such a noob in EAW, but I just can't hanlde amout of fronts, their instant T4 bases and I lways have at maximum 1-2 normal fleets ~350 power to handle them. No matter how hard I hit them, they dont feel it, they have giant fleets and golans out of nowhere, they have like infinite credits. And all it on medium!
