For those of you who have never played a Disgaea game, how to explain it... Well the Disgaea games are JRPG table top games, full of obscene jokes were you control a virtual army of different characters, each with a maximum level of 9999. And no, that's not a typo. The level cap really is 9999. And STILL they manage to make a extra boss that's challenging, with stats in the billions.
Disgaea 2 is for both the psp and ps2, how ever if you can I'd suggest the psp version. It has about 4 more classes, more playable characters then I care to count, the main characters from Disgaea 3, skip able cut scenes, and downloadable characters.
This is one of the only games I've ever but over 200 hours into (the other being a Monster Hunter game), simply because when you start leveling up at ridiculous amounts per level, you kinda get addicted to it. So if you ever get the chance, I'd really suggest this game dood!
