The Jan Willem Nijman talk was excellent, thanks for posting it!

To those that haven't seen it yet, he iterates a boring game prototype into something that actually seems worthwhile. And all he does is add tiny things that seem inconsequential at first. Stuff like "make the bullets faster" and "add a muzzle flash".

I was amazed at how big of a difference the small changes made in the end. Adding enough lipstick to a pig actually worked wonderfully.
