If your doing the lessons there's no need to be creative (for now) if you don't know how to draw or paint, or know a bit but would like to open your horizons this is a good thing to dive into (maybe even advanced people can still learn a couple things). When you finish the lessons though and learn a couple techniques, I'm sure you will come up with ideas of your own. But like Vince said, inspiration is all around you. Art is a way for us to see the world through your eyes.
Btw if you had trouble with WDY I don't think you will do well at all with Petit Computer. Do you mean as coming up with ideas or being able to actually make a game?
and I like drawing Nintendo characters, I might end up sending pics of rare obscure Nintendo characters then, but does each drawing take up blocks? Like each Petit Computer game?
