This is the standard price for the game on the PSN Network however in comparison to the prices that stores & ebay have it for (if they have it at all) this is a great deal!
first of all this is a niche game... so some may love it and others may not http://www.youtube.com/watch?v=oeHZZ4bScyA&feature=related
This is a strategy rpg by developer nippon ichi. One of the best and unique games I have played to date. It is a port of the ps2 game Disgaea: Hour of Darkness but also features an additional Etna mode.
One of the most notable things about this game is the ability to level up your characters to lvl.9999!!!! :)
talk about longetivity lol
You are also able to create your own 'army' to fight alongside you. most rpgs I have played only allow you to use story characters.

PS. This can be downloaded via your PSP, PS3 or even your PC
