Here's my experience in a nutshell:
more houserules = more problems.
Without getting into a multitude of examples, I think it boils down to what constitutes the common understanding of the game. Anyone can see a published rule in a book and accept it (although reluctantly at times). An RPG house rule often only exists in the mind of the DM. Even a DM's "published" house rules are not as easily accepted. I think there's just something magical about something being published and "official".
To continue the MOnopoly example, I've long likened Free Parking money to RPG HRs. I prefer to play RAW, but I've happily played many games with Free Parking. I just want to know beforehand about it, and I better not be the only one who can't hit that jackpot.
Another example is football. Professional players expect games to be called accoring to current NFL rules. Not college. Not high school. Not sand lot. Not what the ref thinks "should" happen or "how it's always worked".
