After playing this for a couple years, a few suggestions. Or ideas :)
I think Underground Factories should be bombable up to half there max value. That would require the Reich to keep Ftrs present to protect them. I usually have at least 3 Ftrs in W GER anyway, to protect the Fleet if i have one :) or just the Ruhr itself. But it would simulate the Air War better imo.
Also think the Air battle should only last 2 Rds instead of unlimited. This gives the Defender a couple chances at shooting down the attackers, but not endless.
Some Bombers would fly through the defending Ftrs and make it to there target. Only to be shot at by AA lol
The other thing I’ve noticed, is i don’t use USA Paratroopers. They seem too expensive to transport. Would be better off just hauling a Artillery imo.
I wonder if giving them the ability to transform from Infantry the way the Marines can, would be worth exploring. Or maybe you already have :)
Thinking limit them to UK proper and only 2 a turn ? Idk. Maybe that unbalances Western Europe too much ?
Anyway, not to sound critical in a bad way or anything :) Best Mod out there in my opinion :)
