One to watch in its early stages here:
Moodle HQ developer John Okely has made a plugin for turning quiz questions into a retro-spaceship-like-shooting game. It's currently "proof of concept" and available from his github, but your admin can install it in the usual way, very easily, and it's simple to set up. Basically, when you add an instance of the Quizventure into your course, it will pick up all the multiple choice questions in your question bank and build them into the game. I made a grammar one:
(Actually, I was going to make a mini screencast demonstrating it until I realised I was totally hopeless at the game )
So if you are a teacher with students who enjoy playing such games, it's a simple and fun activity to consolidate knowledge. Last term I took a group of ten 14 year old boys once a week and worked with them to create Moodle quiz questions for a Functional Skills ICT course they were doing. We looked at what made a "good" quiz question, how to create questions in Moodle and how to turn them into a quiz and then they tried out each others' quizzes and peer -assessed them. I can well imagine these boys would be delighted to play the game with their quiz questions (which they are happy for me to share eventually on Moodle.net .)
Caveats: there are no sound effects and you can't choose the questions, but it's worth keeping an eye on...
