Tech research in general has always bugged me in strategy games... isn't there any way to implement tech 'leakage' or knowledge sharing across borders? I'm sure that the Ottoman Empire (or whatever) didn't have to re-invent the steam engine from scratch just to build a railroad across the country. It makes more sense to be reticent with technologies in the modern world, but not so much in earlier ages, methinks. The earlier back you go the easier it should be for techs to slip from your greasy fingers.
