Regular meetup for Game Designers - always on the first monday each month. We'll pick one advanced design topic for each meeting and discuss it in the group (talks / slides are very welcome). After that we'll hang out, share a few drinks and have a good time.
Topic for the first meeting: The MDA model (mechanics, dynamics, aesthetics) and how to use it in day-to-day design life. You might want to read this: http://www.cs.northwestern.edu/~hunicke/MDA.pdf . You might want to watch this: http://www.youtube.com/watch?v=uepAJ-rqJKA .
