Monopoly and Risk were huge staple board games in my family. They always ended in fighting and strife. Good times, good times...
A few other interesting ones we used to play as kids.
-4 way chess (uses 5 boards and 4 sets of pieces)
-LEGO Time Cruisers
-Balderdash
-Star Wars - The Battle for Naboo
Some older board games I’ve only discovered in the last few years... Scotland Yard, Clue, Axis and Allies (1942).
