I have started a game on the lowest level and havn't had problems expanding, finding resources, but as the game goes on, it seems I am spending more than I make. I have to keep putting the science gets lower and lower. I don't have that big of an army, I only have 1 army of horsemen and have won a war with them and some catapults. I now own most of North America in the huge world map, but still, my economy keeps dieing. I can only put science so low before I am overtaken or even go bankrupt. How do I make more money? I have looked at tax collectors, but they only get like 1 per persion. I put most of my guys on science, but then they only get 1 science. Is it better to make more money and raise science funding? Still though, after changing all my science to tax collecting I am only at 20% science funding and getting more negative every turn. Building maintenance seems to be the killer. Can't I build every building in every city? Shouldn't the good effects outwiegh the maintenance?
