My DD8 has really gotten into Cato's Hike. I started her with that one, but I really don't know the difference between them all. I've heard so much about Scratch that I was going to start her on that one. The other one that looked interesting was Stencyl because you can make video games and share them. Does anyone know the difference between Cato's Hike, Scratch, and Stencyl? Is there a reason to choose one over the other?
