I know we talked about Disgaea 3 in the podcast, but I wanna talk about it here. I picked it up pretty recently, and am chilling on the start of chapter 6, with mao around 60. It's got that good ol disgaea feeling to it, and i'm enjoying it muchly. Question though, I need stages to grind! what gives out the awesome expz?! Mao's heart isn't cutting it because it's too gd slow.
