A better example Joe could've provided is Monochromic Chess, where all piece must land on the same color of the square they started from; i.e. Knights can't move. It's a famous fairy condition in problems. A pretty implementation of this rule into a game is Alice Liliputian Monochromic Chess (not sure about the order of adjectives) by, I guess, Peter Aronson. Check it out.
I don't think Bland Chess is the reason Chess players hate Chess Variants. I think the real reason is Bughouse, and that they are too narrow minded.
