Have you ever had a soundtrack of a video game that created a powerful emotion in you (sadness, joy, excitement, etc) ? The kind of soundtrack that 10, 20 or 30 years later will have the same effect on you ?
For me it would be the soundtrack of Final Fantasy VI. It all started with this game's music. But of course there are many others (or FF, metroid games, zelda, castlevania, bayonetta, etc).
What about you ?
