If you typically have a compulsion that you have to see all the content in a game, P4G is going to be a miserable experience. There’s a way to complete all the S-Links on the first run, but it requires a ton of early gameplay sacrifice, min/maxing, and lot of shuffling Personas around. If you want to add in seeing all the romances at once, the game’s going to literally punish you for doing that. Making meaningful decisions with your time is a core part of the series formula.

That said, it’s all but trivial to see the “true” ending in P4G. There’s just a small, specific requirement you have to meet.

As to the series (and related games) in general, it’s much easier to see everything in Persona 5 Royal and Metaphor: ReFantazio. You’ll need either a guide or to know a few of the time-saving strategies in P5R, but Metaphor is pretty straightforward with it. I recently finished both with plenty of calendar time to spare after seeing all the content.

By the way, feel free to ask questions like this in a post! We don’t have nearly enough discussion posts, I think.
