I did not confuse inspiration and fanfiction. You need to ask for permission either way because you will always take elements from the case.
We are aware that this isn’t how copyright or fair use or any of these systems work instead it’s how this game jam is run. We respect the famicase artists and if you want to participate you should too.
You can take any cart and run with it how far you want to go but still ask in the beginning if the creator is okay with it.
As I said in the post most of the artist love the idea and are happy to help with your game. It isn’t a chore to be respectful instead it can be quiet fun to exchange ideas or asking for their inspiration on the cart. Also I never had someone say no. But a lot of them I could credit on the games itch pages for helping me.
So please just ask! It isn’t hard, nobody tries to eat you. Instead you can connect a little bit with some really cool people.
