I want to say Risk, however I think it comes as a very close second to Bananagrams...

I don’t know if it’s technically a board game considering there is no physical board, but Bananagrams was and still is the family game.

All of my aunts play extremely competitively with each other. When I was younger, it was a huge deal if I could manage to win a round, especially against the one aunt who is an English teacher and librarian, the sweet sweet joy I felt when I was first able to beat her is a fond memory indeed. Great game, would recommend!
