I am trying to play as England, but can't get anywhere - the Scots end up taking Flanders (every time I try I get beaten by the big rebel army with Frankish Knights- the scots always beat them, no problem), my priests always go heretic and my nobles are obsessed with Rennes, which only gives the French and the scots time to build up and double team me. Can't make it much past 40 turns.
Any suggestions?
