There are definitely games that I enjoy more as I grow older. When I was younger, I couldn't stand the more lighthearted/simple games, but now I can appreciate the fact that they let you turn your brain largely off and just enjoy the fluff. There are of course things I enjoy less....stuff like the mofumofu system in Mojuutsukai, which I used to find really cute, are now just kinda bland and obvious ASMR marketing to me.
I don't think my taste in love interests really changed.....it's more like, my appreciation of different kinds of love interests expanded? When I was younger I appreciated fewer types of people than I do now, lol.
Looking at your age, it's a pretty normal time to transition from teenage lifestyle to adult lifestyle, and I think it's natural that people would think you'd end up feeling like a different person from who you used to be and end up enjoying different things...which really isn't the case! You WILL remain largely the same person inside, just with some shifts in values and understanding that changes how you interact with the world. There ARE some things that age badly and you can't really go back to without noticing how badly it aged, but a lot of things do age like fine wine actually and there were totally fiction I enjoyed in my teens that I now enjoy more because I couldn't appreciate some stuff in them without some life experience.
And cute romances are always cute.
