Today's Irregular Webcomic strip includes an absolutely epic rant by David Morgan-Mar about the evils of Monopoly. Not monopolies in business, but the game Monopoly. (Scroll down beneath the comic strip to behold its ranty majesty.)
What's particularly interesting is that all the things people dislike about Monopoly were conscious design decisions by its creator. Elizabeth Magie was a follower of the "single tax" movement founded by Henry George, and she designed "The Landlord's Game" to show the evils of private ownership of land -- following orthodox 19th century crackpot economic doctrine, the rich gradually acquire all the land and everyone else winds up penniless. In other words, it's supposed to be no fun. But millions (possibly billions) of people have played it for a century despite that.
They should all be playing Bone Wars instead.
