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 was an interesting resource to consider and manage. It made it so I had be smart about repairs and upgrades (especially late game). Also stopped me from just spamming special weapons all game.
