Honestly, it's the sim-style ones for me. The Tokimeki Memorial Girl's Side series and the La Corda d'Oro series are the ones I keep coming back to. There's so much random dialogue in those games that I still stumble on lines I've never seen before, even after countless playthroughs lol.
These days, I keep replaying Kyoya's Route from Wakudeki.....if that counts hahahaha but the overall relaxing atmosphere, chill vibe, and the music made me stick to it again and again! I enjoy the group dynamic between the boys especially, and I adore Sayo-chan too
So many but sometimes just a few favorate routes. Recently playing AMNESIA beucase that was on PSP so need to create saving data on NS. Still excellent story comparing to others even after so many years.
Uta no Prince-sama is my comfort game. No matter how many times I replay, I still feel the same excitement as the first time I played it. It never gets old.
