I say that stronghold 1 is better than stronghold crusader, and here are the reasons:
Stronghold crusader was made to be a quick game with lots of action, that’s why firefly made economy easier in crusader:
In multiplayer mode, stronghold crusader players use mostly horsearchers, shields, assasins and catapults while in stronghold 1 every troop has it’s own role. Example spearmen and pikemen are strong against knights, but weak against macemen. So here you get to use all soldiers.
Economy in stronghold 1 is harder. And there are no mercenaries, so you have to produce every weapon yourself.
Stronghold 1 is more balanced than crusader, example – in stronghold crusader shields move at the same speed as knights (What the hell?)
The only downside to stronghold1 is that it does not support teams of 3 or 4 players.
