This came up in discussion with another designer the other day (after a comment along the lines of more game design students these days being familiar with Thomas Kinkade than Reiner Knizia). I thought it would be an interesting open question to repost here.
If you're unfamiliar with Thomas Kinkade, he is one of the more (in)famous painters alive today. You might want to read his Wikipedia entry here to put yourself in the right frame of mind to consider this question.
The question: to the extent that game design is an art form, what game designer is the equivalent of Thomas Kinkade? Or, more succinctly:
Painting : Thomas Kinkade :: Game Design : ???
Some people might consider the label "Kinkade of Games" to be a great compliment. Others might consider it a grave insult. For this reason, I won't hold it against anyone if they choose to comment anonymously.
