Makai Kingdom was made by NIS as well, hence prinnies, and the Idea of the Netherworld and the reoccuring overlords in Disgaea 2 (you'd see them in the ned/beggining episode snippets). I enjoyed almost all of the games by nis; Disgaea 1-2, Phantom Brave and Makai Kingdom, I just couldn't get into Atelier Iris for some reason.

BUY DISGAEA...if you can find it. If not, buy it off of their site for 39.99 or something like that. And then spend $20 on a prinny doll like I did. :cD

The first Disgaea and Makai Kingdom are the ONLY games that I liked playing more than the Final Fantasy series. Phantom Brave tied with the top Final Fantasies and Disgaea 2 was kind of a So-So. Funny, but too much of a lovey dovey story line. It was very Japanese, about family and honor and the like. Still fun.

Also, to beat it with little problems (i.e. surviving with one character, you'd have to be at level 80 with all of them. because at the end the boss is surrounded by enemies with attacks that go over a large grid area. Very annoying.
