There are a lot of ways we design games. The best designs come from the crazy and later are vetted with a group of awesome people. One of the coolest companies to create awesome is Double Fine. For their kick starter they started a documentary on the creation of Double Fine Adventure:
I recommend anyone to watch both of these. This is the type environment all of us in the industry would like to be part of from a creative side. This is no small feat since every company has it’s own dynamics and often these are business related since in the end we need to pay the bills. Double Fine has been talented and lucky enough to blaze their own path in several ways.
Hats off to you Double Fine.
