Well, I have feeling that Project D is not aRPG. Maybe its more of RTS.

Maybe the game is build around managing your Battle tower. You rule there, you hire henchmen, send them on quests, create items and creatures, build defense, help to rebuild nearby town and defend both your tower and town. So its hybrid RTS + RPG. Maybe there is even an construction of zeppelins as ingame element, so there is even some kind of arcade simulator, if you can fly with them.

Or instead of Battle tower you rule in some small town.

Am I close to the truth? smile
