if ur playing as England, make a rapid expansion, i.e. leave like 3 guys in ur settlements, send the rest upwards gainst teh scots. send ur army near caen to rennes in the north west corner. make peace with the french, u dont want to fight france yet. capture antwerp and bruges. by then u hav a good hold. make an alliance with the pope. it'll help HEAPS!!!!!
i play as france. thus i basically capture all of mainland france plus 2 states in spain, florence, (Bologna), stauffen,(metz), Antwerp and Bruges just by rly rapid expansion in the first ~15 turns.
bien des choses chez vous!
