Patient Gamers

The entire Ace Combat series, particularly from 4 onward are almost entirely comprised of the best music I've ever heard. I couldn't reccomend all the specific tracks because i'd probably hit some sort of character limit but each game has a "flagship" track which I'll highlight here:

• Rex Tremendae + Megalith -Agnus Dei-
• The Unsung War (special mention to First Flight)
• Zero
• The Liberation of Gracemeria
• Daredevil

Also will reccomend both the Metal Gear Saga (e.g. ...Metal Gear Saga)

And the Boss themes from Metal Gear Rising

• Rules of Nature
• I'm My Own Master Now
• A Stranger I Remain
• The Stains of Time
• Red Sun
• The Only Thing I Know For Reap
• Collective Consciousness
• It Has To Be This Way

I love the soundtrack of underdogs. The song i like the most is ready for war (wraz. Remix) by Dominus and magugu. It feels really good in the game when you get in the big boy arena and this song starts.

Not For Broadcast

Hi-Fi Rush

Lollipop Chainsaw

Kingdom Hearts

Guitar Hero 3

I just finished Frostpunk recently and have to say I really enjoyed the soundtrack.

One that sicks in my memory years after playing it is the soundtrack for Expeditions: Conquistador.

Gonna list 2 that deserve the "great soundtrack" tag on steam:

• Assault Android Cactus - twin stick shooter/bullet hell with cute android girls blasting robots. Techno stuff, with my 2 favorite tracks being Liquorice (it's divided in 3 "acts" as it's a boss music) and Assault
• Cloudbuilt - 3D platformer with focus on speed. I suck at this game, but the tracks are amazing, with my fave being Aurora

Someone else mentioned Unreal 1, but I gotta say, Unreal Tournament 2004 has some absolute bangers, like Morpheus3, Hyperblast Redux, Level11 and Convoy

Rebel Galaxy - country rock genre? Very unique and different sort of music.

Trine 1 & 2 + Transport Fever 1 - instrumental background music good for concentration, working, studying or just relaxing.
