the best hint is to do many quests to gain a lot of money. when you run into rogues along the way, delivering packages to towns, never use your hero: always let your troops do the work. after winning these skirmishes, sell the salvaged items for lots of money! soon you will have enough money to buy some troops. do things one at a time. the first city to consider conquering is Lutetia, then Arrteium, then Ravenna. Keep doing quests until you have enough money to stock up on all those new troops.
its actually a pretty good game..
