I know that I am in the minority. Plenty of themes I would love, few I would buy because at the end of the day, theme doesn't make the game. How the theme is integrated and the gameplay itself makes the game. I am actually attracted to original themes if they are done right.

Tons of crap games made from popular licenses, but when most of your buyers are buying based on teh name alone, sight unseen, of course theme is king.
