Hi, thank you for your question. If the user interface is included in the artbook, please purchase the premium license. I say this because I want the license to remain fair to unfiction creators, as this framework can also be used by artists creating unfiction (which is a non-existent game where the story is presented as a game manual or a Let's Play, etc. that includes screenshots or footage from the game--examples of unfiction include Apple Quest, Bird World, Halfway to Nowhere, Ghostbleed, Valle Verde, and Vermis). If the artbook does not include the user interface, then non-premium license version can be used instead.
