Statues

[PumpkinKing]

Ok, so I don't know how well this will be received, but here goes.
My idea is to add statues to the game that offer certain benefits when you place them in your dungeon. You would produce them in your workshop, and they would be placed like traps would. Benefits may be increased happiness when close to one, increased productivity, speed boost (for imps), and maybe a few could even be secretly traps/triggers. It would also add a certain character to your dungeon, and would add something more exciting to look at then walls and torches.
Well, that's it. I hope you guys like it.

My own old "Trophy" Special suggestion is essentially this, except as pre-existing map objects, rather than workshop things to be placed. In my opinion that makes them less exploitable. There are other difference of course. Also there are lots of things they could do. Take a gander. Its quite extensive.

Intention is the same aswell:

Many of the bonuses in previous Dungeon Keepers have consisted on one-time bonuses like magic boxes and rooms full of claimable neutral creatures. This seeks to add an additional more ongoing, strategic effect to the mechanic of specials and increase their impact on the battle over time without unbalancing it. In addition it also seeks to add visual and game-play diversity - making the underworld into a deeper, richer, more satisfying place.

Beat ya to it

Oh, ok.
Sorry to step on your feet there, cookie.
