Hah! Yes, and there's a lot to be said for actual games which require problem solving in order to progress. And even more those which result in something unique being created as the outcome. In fact, your comment has made me thought of an educational type game which when completed results in a 3D model file produced, which when printed, can be manipulated a certain way to provide access to the next stage in the game. Right.. I'm gonna think some more about this. Meanwhile, someone else reading this can steal the idea, it's all good, I'll probably never do it anyway 'cos I'm too busy playing games every single day.
