Personally, I'm a huge fan of Hollow Knight, Ori and the (Blind Forest/Will of the Wisps), and Kingdom Hearts. Orchestral soundtracks are just something else...
I love Amplitude Studios soundtracks (Endless Legend, Endless Space 1&2, Humankind). They're great background music while thinking about stuff (like at work). Though maybe I just got Pavlov'd into thinking that since they're strategy games 😅
Also, Persona 4! The soundtrack is so nostalgic and reminds me of my childhood somehow.
