definetely Life Is Strange

Gargoyle's Quest - Cover Medley

Recently I really enjoyed the VirtuaVerse soundtrack , but I was a fan of Master Boot Record's music before.
I also love the soundtrack of The Yawhg. Also the soundtrack of Brütal Legend. Let's not forget about The Binding of Isaac: Rebirth. Rocket League also comes to mind, but that's not really a soundtrack for the game, more like random different songs.
These are just the first few coming to mind, but there are probably a lot of others that I can't think of right now.

Hollow Knight has very good and fitting ambience music
