darthvictorbr: There are any NWN1 mod that allow you do manage your stronghold, go in missions to loot and sell the loot to improve constructions, defend your stronghold agaisnt hordes of enemies and etc? With different enemies, other's kingdoms invasions, undead invasions, "outsider"/demon invasions, etc?
Never heard of one with Castle, but as far as I remeber there was one module either for nwn or nwn2 where you managed Amn thief guild. You found informants, strongarmed merchants and etc. But I remember it coused insane slowdown dew to extremely huge and filled map. Can try to find it, but it specially made for evil thief with a lot of thief skills
Also there is Dark Water series for Nwn2, where after first act you get to manage your own personal pirate ship, with treasurehunting and abordages. I'd say in world after global flood you own personal ship is close enough to Stronghold
