Robin Hunicke, Malcolm Ryan, and Ben Smith are hosting a design workshop. In it, Marc LeBlanc's mechanics-dynamics-aesthetic's (MDA) framework is applied to a practical (and fun) design challenge. Essentially, MDA relates rules to play, and play to feelings. Being keen on this framework, I'm assisting the workshop, and we would be happy to help you there: GDC, Tuesday at 10 in Room 2002, West hall. See details.
And for those of you that rehearsed one of the exercises, thank you!
