The framework used is but a hammer anyway, its in the actual creation of a game where the real fun is.
As an exercise I tend to make juniors I'm training in Java development to create a command prompt hangman, polished as far as that is possible (neat textual output, using an actual word dictionary file, creating a neatly packaged application which can be executed with a single click, etc.). Its amazing to see their faces light up when people in the company start to seriously play it and provide positive feedback and even enhancement requests.
Yeah I know. I've been coding in pure Java for ages though. My friend's been bugging me to use a library and i really should be using one by now.
It's awesome to hear new people getting into programming and enjoying it!
