Do you want money or will you make it for free?
Viewing post in Need music for your game? I've got you!
Here's what I have:
IF for a game jam and there IS a money prize, then 5%
IF for a game jam and there IS NOT a money prize, then free
IF creating an original game WITHOUT the push of a game jam, THEN 5% of profit
Details can be discussed but that is normally the way I operate according to money in terms of the type of game
