I’ve yet to manage it, but now Disgaea 6 is making its way to PC.
it’s possible for you to find the announcement trailer below.
Disgaea 6’s most flashy innovation was switching the 2D isometric art for fully 3D battlefields.

It looks… worse, honestly?
Otherwise it’s a similar story.
It’s the battles and levelling that are compelling, however.

You will spend a lot of time managing things via menus, but that’s part of the fun.
Disgaea 6 Complete will launch sometime this summer viaSteam, where you’ll find some extra screenshots and details.
I bet Ed would write a really interesting review of it and I hope he does.
