I met up with a drummer I know a few weeks back for coffee. He's been teaching Scratch at a school and of course I have been playing around with NESmaker. I'm not familiar with Scratch, aside from what this guy showed me. I thought it looked quite useful for teaching people about programming / coding, as opposed to having to learn it "the hard way" like I had done when I was studying Comp Sci in 2004. That being said, the stuff he was doing felt easy and aside from you mentioning it, I would have thought that Scratch was just something designed for kids.
If you backed the KS you might have paid more money, but the $39 or whatever was the best purchase I've made in years. There are definitely things that annoy me about the program, but when I see other people creating AAA bangers using NESmaker as a base, it just gives me something to work for and strive for on my own projects - all of which would have never come about, if I were doing it in the way that guys like Chris Covell, Sivak, or even Khan were doing it.
