There's really no other way to make Huns the threat they should be other than cheating.
No, no. There is.
You can't, as a player NOT huns, kill them off. The huns have, as AI, NO Upkeep, aswell as spawning hordes. I'm allied to everyone in the steppe zones, and I've spent most of the game counting and following Hunnic Hordes to merc them and they are pulling them out their ass in the middle of the steppe.
So:
A) Spawning them(cause Attila has spawned)
B) They have some kinda camp hiding in the steppes just pumping troops, yet none of their armies in Europe get replenished(which they should if they have a camp)
Only 2 possible options. B) seems unlikely based on what I've seen. (it's very possible, that the AI is gettting them spawned, probably every time i "kill" attila.)
Had my first crash today too. Took a settlement, and then BLACK SCREEN and a non-responsive game.
