I would have to say Disgaea. It was the only one out of those that actually made me feel for the characters. I would have liked Makai Kingdom if only it had more story segments instead of just being map after map of killing a bunch of units with no real reason except to get the universe back under your control. At least in Disgaea you were provided with some various, funny, and extremely random scenes. Like the Mid-boss for instance, "I have attained super speed due to my training in 100-ton boxers!!!". Truely great stuff
