2001's Stronghold was a very good, and very European game. Finally you could build up an entire castle from the ground up, man the walls with your units, and manage the feudal economy to support all of it. It was the kind of game they go nuts over in countries like Germany, but thankfully it became pretty popular all over the world.
Other than Stronghold: Crusader the spin-offs and direct sequel were not very well-received, and Firefly's games in general weren't particularly great for the past 8 years or so. Now, ten years after the first game, Firefly is back with Stronghold 3.
