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.
I burnt out in Hollow Knight too and was probably around mid game. Crisis Core is just a much shorter game, I think I finished it in a day or two. I'd recommend playing FF7, or any JRPG from that era through an emulator so you can speed up the combat.
