While this seems like good advice, there are some really bad games that lots of people play and the only reason I can come up with for why they do is "tradition". Monopoly has many "game design" flaws (not the least of which is that people don't play by the RAW) and yet, everyone has a copy (or knows someone who does) and has probably played it. In the words of Vizzini, "Inconceivable".
And if anyone cares, the main design flaw with monopoly is early exit: If you sit down with a group to play Monopoly, you can go bankrupt in the early going and are no longer in the game while your friends continue playing. As the game continues the number of players continues to dwindle meaning the net fun provided by monopoly decreases over time.
