I really want to play a Final Fantasy game at some point, but always seem to find something else play. Same thing goes for Dragon Quest games. I could ask everyone here which game from each series you recommend, but would I actually play it? Probably not. 😔
As for a single game I own, I will probably never play Disgaea 5. It's been so long since I bought it.
Valkyria Chronicles, I always start it then bail because the mechanics are so clunky.
Experience it vicariously through KBash's excellent video
Edit: wrong series lol nevermind. I still recommend watching his video on Valkyrie Profile
