OUCH at Disgaea 3 trophies... Not really easy !
I'm around level 600 now with 2 caracters and just got to House of Ordeal 4 (not tried yet)... Caracters are REALLY in need of more power to finish all the crazy "hidden" maps (dimension X, HoO, diez gentlemen and co... !)
This game has really a LOT of content !
