>I guess I should be more specific. If I get kicked off of Fortnite, can I play in Fortnite’s sandbox?

There are more then 1 alternatives to Fortnite but I can't name them. This is a bad example, you compare 1 free game with a store. Stay on topic and let/s compare stores like Google Play, Steam, GOG etc. Is Steam taking 30% if you buy some skin in a game? Is GOG doing that? Are this stores blocking you showing a text with a link to your website purchase page?
