The Disgaea 4 & 5 Complete games hit the sweet spot, where iteration has refined the core gameplay loop, but they haven't dumbed down. Speaking of, DIsgaea 6 kinda dropped the ball by adding auto-battling. (7's ratings seem better, but I haven't given it a chance. I reserve the right to pick up the complete edition, but shelling out for assloads of DLC when I can just grind prior games is a hard pass.)

EDIT: And, just for the record, the current steam sale has Disgaea 1 & 2 for sale at the 4 dollar price point. An absolute steal from a dollar per hour standpoint.
