I want to make a game, and free help would be amazing, but if I get help from people in the collaboration section of the forum, can I still sell my game commercially?
It’s completely up to the people involved. I think you’ll struggle to get people to help you create a commercial game without at least giving them a percentage of the profits, but it’s completely dependent on what you decide between yourselves, just make sure they know you’re planning to sell the game commercially.
