One of the best parts about Dungeon Keeper (aside from building your underground fortress) was the light hearted sense of humour. I feel this kind of humour could greatly benefit Castle Story.

Giving your little Bricktron dudes some character and emotions could go such a long way into making them more fun to interact with. Having them need food, rest and diversions (Tavern?) could open whole new levels of fun and shenanigans. Imagine one of those poor guys being set on fire, and see him running about aimlessly, arms flailing in feeble attempts to put himself out. Cute little screams could enhance this effect. Imagine the dudes getting into drunken brawls when consuming beverages from the tavern. One of the dudes could be all alone in the dark, he could be shivering in fear, being slightly paranoid (glancing left and right nervously).

All these emotions and needs allows you as the player to feel a sense of maternal protectiveness that compels you to help them when they are in need (or if you're a devious bastard, put them in dire situations on a regular basis).

Also, being able to dig underground and line the cavern walls with brick re-enforcements, permitting underground fortresses would also be cool! Training dummies, archery targets, traps and other neat little things would all add depth to the game.

What say you, fellow keepers?
