If some OSTs that you consider great are missing, I probably just haven’t heard them yet—there are still plenty of soundtracks I haven’t discovered. Also, I haven’t listened to every soundtrack on this list in full. For many of these games, I’ve probably only heard around half of the OST, but I do have a lot of tracks from them in my playlist and I’ve listened to most of their well-known themes.
