ooh ooh i got one this one's really simple but it can be a super cool thing to add into your songs if you're making a song for something based off of a video game, go to your browser of choice and see if that game has a soundfont! it's always super cool to hear instruments from the game in a song based on the game you could also use sound effects from the game for things like percussion and instruments you can't find in the soundfont! Fire_Mario_Fan's Mario Mix series does this super well! https://youtu.be/L75oNUBG_58 for example, this song does the sound effect trick, as well as use the sm64 soundfont for both its opponent vocals and instrumental!
