I rather liked the first 2 where the only theme was being a parody of RPGs, but that said while I didn't care for the whole school theme from Disgaea 3, Disgaea 4 is a great game and the political theme is a little downplayed; and to be honest felt like more of a natural evolution for the series given the whole courts and senate stuff from previous games.
But all that said, I had this idea in my head while playing Disgaea 4 of a horror movie theme. In other words a Netherworld, knowing that few humans believe in demons creating their own horror movies to gather fear energy from the human world.
we could also expand on the sci-fi angle and have a Netherworld that is more advanced (we certainly saw signs of this in Disgaea 2 with the Overlords using space ships).
