Hey dude, i think you're onto something great with this game and your ideas about the third person perspective add on. I think you could go even farther and make it a 1st person perspective, that's the kind of immersion i'd love to see for this. I think you could also go a step further and be able to DRH from your own dungeon that you build, out to other dungeons, kind of how you can send individuals out on quests.. you could go out, capture individuals, acquire resources or technology, and bring them back to the dungeon you built.
I love the game. It's awesome. Keep up the good work, whatever you decide to do with it!
Literally one of the most exciting games around in terms of features and what you can "do" in game.
