I would love nothing then to to just pick and choose specific tracks... but I'd be here all day linking things. So I suppose I'll just pick five soundtracks as a whole.
Kingdom Hearts Birth by Sleep Did not even need to think about it, hands done Birth by Sleep. The best of Kingdom Hearts.
Final Fantasy 7: Crisis Core I feel like I should link a couple of specific tracks for an example. 1 2 3 4 5
Mass Effect Trilogy I couldn't pick just one, I like all of them, sadly this one doesn't include Andromeda, but I'd like to give that a shout out as it is good.
Warriors Orochi 1/2 It's the best of two worlds, I don't need to pick either Samurai Warriors or Dynasty Warriors thanks to Warriors Orochi
Assassin's Creed Rogue It's always hard trying to pick a single game from a franchise. But I've always found myself listening to Rogue the most.
