One of my favorite video game soundtracks has to be Metal Gear Rising Revengeance. It fits so well and honestly listening to it outside of playing the game is very satisfying.
Fan of Metroidvania type games? Then you should get this alternate universe version of Metroid, its a blast. And the creator of the game also composed the soundtrack. Which is equally good.
I've played Axiom Verge. Not a whole lot, maybe an hour or so, but that's a really cool game. Great music.

Assassin's Theme and GTA had awesome music. Replaying Witcher 3, and feeling a lot of great music in there too. Like this one ""
