This is a dumb question I think, but if I buy Assets from the Unity Asset Store and make a game with them, can I make money off of those Games Legally? On the App Store? What about the default FPS controller, and other default assets (Textures, Prefabs, Scripts) ?
As long as the creator doesn’t specify specific restrictions, any asset from the Unity Asset Store is able to be used in any way you need, including modifying and using in a paid game.
