Hey, was gonna look at picking up Mighty Empires for some campaign play, but was wondering if I could get a few opinions first. these questions apply to people who have purchased and played Mighty Empires: was it worth the cost you payed? how detailed and useful is the 'campaign' structure?

Would it be more worth my while to just build my own campaign board and write my own campaigns using the maps in the rulebook and army books as a basis for scale and proper geography (well as proper as it can get in Warhammer)? it would save me a hell of alot of money if I did... so is it worth buying?

thanks in advance.
