Fans of historical strategy/building games on the PC might recall the Castles series. Earlier this year, Interplay brought Castles to Steam leaving many to wonder when its expanded sequel would arrive.

Today's the day as now Castles II: Siege & Conquest is available for the platform. It takes place in 1311 and allows players to create a fortress however they see fit before engaging in turn-based battles.

Castles II is currently discounted down to $5.99 on Steam. With that said, you can grab the Castles 1 + 2 bundle on GOG for a total of $9.99, which is cheaper than picking up both via Steam.
