Too many games including some of my all time favorites:
FF4, FF5, FF6, FF7, SotN, Super Metroid, OoT, ALttP, Majora's Mask, Chrono Trigger, Chrono Cross, Xenogears, Suikoden 2, Touhou 8, Ys Origin, ICO, Persona 3, Okami (played it for a few minutes on PS2, then finished in on PS5 two decades later), etc.
When I enter "retro mode", I often start with weaker games to adjust in preparation to well received games that I missed out on. Rather than going straight to them from modern games, sometimes I give myself time to adjust to the old standards. In some respects, older games remain superior when played today for the first time. But in other respects, I think it's just better to give yourself time so they can feel a little closer to how they would have felt if you played them back in the day. Obviously, it's impossible to replicate that, but this method works for me.
Retro gaming is cool and is one of the reasons I'm not all that worried about modern gaming crashing down. I could just go back to trying countless beloved games that I never got to experience.
