Monopoly's just a classic game, even though when me and my friends play we get overly competitive. Like loud fights and arguments are breaking out. One time it came to the point where I had a little money left and I was debating on buying a property, so I called my dad's best friend, who deals in real estate, for his advice.
Another fun one is Truth or Dare Jenga, because its so stupid. I still remember my friend's quote during the game "Looks like I'll have to........SING A SONG! UH OH! WE'RE CRAZY GENERATION X-ERS! WHOOOO!"
Scattergories is pretty intense too.
