First of all, I'm not knowledgeable in this area. My question is would charging money for my game be legal? (Of course it would have to be your own creation.) In the U.S. there's taxes which are automatically deducted from your pay check and selling Lemonade on a street is illegal without a business license. So would I need business license to make money from my game legally? Or is it handled more so like casually giving someone money?
