im playing BI. i find that it is not a very good game. i love the franks, and it does have some cool features, but overall, its lacking. i do love the frank campaign and units, as i said, but i also like the WRE. although it takes a lot of micromanaging at the beginning of the campaign, if you get your empire stable, you can expand anywhere, will have pretty decent trade and money income, armis to battle hordes. and when you take ERE, its only fitting that the roman empire's capital be ROME.
