Not just the playing of games can facilitate learning - also the creation of new games can be a fun and challenging approach to activate the learning process. Remixing play offers impulses and ideas to work on own game ideas - by yourself or in groups.
It is pretty straight-forward: you get a random topic and game idea (based on well-known existing games), which students should combine into a new game. It's the perfect exercise to train the adaptation of theory ( = game features) into practice ( = actual gaming experience).
The free game can be found here. It can offer a quick exercise but also be used as the basis for a bigger project.
