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.
It started to feel like I was running out of stuff to do on day 2, but when the second area opened up there was more than enough to do to fill each day, so I got hooked again.
