Not much here that hasn't already been said. XL mod if you want a long-running GA game.

BKB's mod adds a ton more buildings and a few agents, i.e. axe-smith tech. tree, Jewish Master Merchants, Heretic Priests, etc.

Is it just me, or could XL's cash-strapped economy greatly benefit from BKB's fisheries, foresters, and other money-making enterprises...?
