im not sure if this has happened with anyone else but when i play the normal civ3 game i am war crazy and go for monarchy as fast as possible and all the war tech and i noticed when i am an heroic difficulty and am already on monarchy and have so many units my gold is -100 per turn i noticed if i keep building units like no tomarrow my gold eventualy goes up it doesn't make sense to me like after 200 units later my gold is +500 instead of -1000
