Short of roms getting wiped off the surface internet entirely (which is doubtful given the demand, especially as long as countries like Glorious Brazil continue to exist) I reckon it should stay relatively accessible.
I always associate Mitsuda with the Chrono games myself, though I do like his work on Xeno as well. Kajiura’s stuff can get a bit same-y but I love her unique style enough to not be bothered by it.
There’s just too much stuff now. These days I approach each game I play like it might be my last. I also have a wider range of interests than I used to so it’s hard to devote time to “pretty good” games when I could devote it to “this inspires me” games.
I never played IW because I’d heard enough about it to put me off, but I did play HR. It’s a very dudebro interpretation of what Deus Ex was about. Not a terrible game on its own, but eh…
Did you also get into David Bowie? Xenosaga got me into his stuff and I still listen to Ziggy Stardust (and Diamond Dogs and Low) all the time.
