Disgaea 5 is not game of the generation. It is really easy to get into. in my opinion it has a really good tutorial to ease you in. Crack that baby open and give it a try
Disgaea has a pretty good tutorial at the start of every game alongside the start of the story, so you should be fine honestly. Might as well go with 5 since you own it.
Thanks. I'll go dust off my copy and give it a spin. That's good to hear there's a tutorial, that was one of the main things I was worried about.
Down the rabbit hole I go!.
