A few years ago, I played a game where you have to defend your castle. You could move inside it, could repair the gates when damaged and leveled up over time. Also you had a few weapon choices, like maces, sword, crossbow, hammer. If I'm not mistaken there were recruitable Soldiers, like mages, archers and knights also... and the buildings for all this were in the castle to approach them.
I'm desperate because I'm unable to find it again... :/
