Not to mention, for Perosna in particular, each Perosna game tells a whole new story, so buying the fifth one is like going to see the fifth movie in a franchise: you know you like the style, and you want to experience a new story in this style. It's also not even a very long series - compare to Final Fantasy, for example, which will soon get its 17th main game (probably more like 25th or something if you included spinoffs).
The way you perceive them does, at least did back in 2023 (or 2013) and earlier.
You pick up, say, original Half Life or something from that time; story-wise it's the same game you remember, but in terms of experience, is nigh-unplayable in its original form now, because you already experienced how decades of progress in videogames look like. Not just in terms of graphics, though that is a big part, but also in terms of UI! Properly mapped controls and GUI behaviors are alone worth looking up/waiting for a remake. And/or, the Nth installment of a game in the same universe.
Every good game has odd control schemes, that doesn't mean it's worn out.
IMO the quality of games has gone greatly downhill, and when I pick up something old like Doom 3, Half Life 2, or Portal, I am staggered by how good they are in comparison to most of the unity based slop which currently passes for games.
Video games don't wear out, you can still play the same software you bought in 2003 today.
