That's great. And, I love that the examples all specify /home/ubuntu as the home directory, so the author is clearly using Linux. This is really cool.

Yes "Your First Game" is a fine place to start even if it tells you to read some other things first. I'm a big fan of diving in to get something running, then searching or backtracking to learn the fundamentals if you need to.

There were a couple of typos in there that I ran into, it shouldn't be too hard with a little programming experience to notice these. I didn't download the finished files because I think typing it out is a much richer learning experience.
