I have been playing civ4 for a while already, I've managed to win in each difficulty until prince, when I started playing prince after I reached about 1000 A.D I was starting to fall behind in technological develpment and as the game moved on it became worse, it happend because my economy fell apart and my science percentage was only 10%
.but I managed to stay alive because of the game's bugs(without patches) that the other civs gave me all their secrets for peace only..
then I installed the patch and i discovered that i couldn't do that thing again, and it became totally impossible for me to play...for example while I had knights they had infantry
so my question is how do I keep my economy and science alive in prince level?
(or maybe i should consider reinstalling the game and playing without patches but that's quite cheating and not interesting)
