We also have those. My son's favorites are Sorry, Yahtzee and Monopoly. He is ruthless at Monopoly.
I'm a little late jumping in but I'm gonna jump in anyway...
My two favorite games are Trivial Pursuit and Monopoly.
My daughter was never actually very good at monopoly, or she was just so much younger that she was always the one to lose first.
Well it's no fun if your out of a family game, and as I was always the banker I would slide money and/or the occasional house out of the bank and into her hand.. it was no big deal everyone knew and it was an unspoken agreement. Playing was what was fun and no sense in her sitting out.
Well, one summer my sister's kids came to stay for a couple weeks and oh wow.. apparently my sister had no such penchant for keeping the children in the game, because when we tried to play monopoly with my niece and nephew, not 20 minutes into the game the boy was crying saying we were cheating and all traumatized because we didn't play "according to the rules" and we were "loud".. (I don't know what that meant other than we were laughing and joking and he wasn't used to it)..
He literally started bawling over the way we played... I was like wow.. no fun in my sister's house I take it.. lol..
