at very hard changing capital costs 5000, at medium or lower 2000, try test how much money it takes
i've never played a hotseat against other players but if you have this "autoresolve_battles = 0" in the default file then yea you should be able to fight against the AI
my settings for single player hotseat campaign, everything plays pretty much like a normal campaign
Code:
[hotseat]
turns = 0
scroll = 0
autoresolve_battles = 0
disable_console = 0
disable_papal_elections = 1
save_prefs = 1
update_ai_camera = 1
validate_diplomacy = 1
[multiplayer]
playable = true
