Art in Prototypes thread. The basic question (and one that comes up fairly frequently among new designers) was "How much effort should be put into the art for a prototype before it gets submitted to publishers?"

This Geeklist provides some side-by-side image comparisons of original prototypes and the now-familiar games that they became.
