I'll try to keep this short, but I need to explain the situation before I ask the question I guess!
Playing at Warlord level in conquests, actually have two games going on this level - in one I'm the Arabs, in the other, I'm the Mayans (love the Javelin Throwers!).
I try not to build the Great Library so I can challenge myself, (though I have captured it in one of the games above). But I find myself in a quandry when the middle ages roll around.
I get to a stage where I fall beind in tech research. I try to trade techs with the AI and am only partially successful. So because I am trying to research these techs, I don't have a lot of money.
But the real issue arrives when my older, more established cities, start getting to the stage where they finish certain improvements or units, and I'm prompted as to what to build next.
Because I don't have a heap of techs, the number of city improvements I have to choose from to build is limited. And because I don't have a lot of money, I don't want to keep building units which cost me $$$ to maintain.
Not only that, some of the improvements also cost $$$ to maintain - for example, I try to steer clear of collesiums because they cost money and I don't really have a lot of happiness issues (roads hooked up to luxs, temples/cathedrals/markets, a MP or two in each town etc)
So my question is multipronged I guess - how do I get out of this type of vicious cycle, but also - what can I put in cities as improvements when I have very few options for those improvements?
Finally - the "building wealth option" - is it an option, what does it exactly do (I know sort of what it does), and are there any benefits/drawbacks to this that experienced players have encountered?
Thanks so much!
