I actually really enjoyed the prototyping reading, mostly because it reinforced and reminded me of some things I should do while prototyping.  In particular, I really liked the part about not just accepting your failures, but loving them.  The idea that you could show off a failure as something that was out there and missed was a good thing to remember.   One thing I hadn’t really thought of for group prototyping was the developing in parallel though.  I think its an awesome idea if the team can do a bit of everything.  I personally love being able to dabble in all parts of game creation, so it really appealed to me.
