Ok continuing on from my last thread, he's a different question.
What is your favourite music from a Video Game?
So for me, there are two answers to this for me.
One: The opening theme songs for the VR Games, I expect you to Die. They are absolute and fantastic, and certainly channel that classic James Bond spy feeling. Cannot help but sing them.
Second, multiple songs from Final Fantasy XIV. To The Edge, Endwalker - Footfalls, Shadowbringers, some of the songs from the Alexander Raids , there's too many to name, but these are all great, and seriously can't stop myself singing along to any of them when they come on.
Megaman without a doubt. Regular and X.
MegaMan 2 especially IMO.
