Stratego! It’s a terrific game for only two people. You probably guessed it by the name, but the game deals a lot of strategy. However, it is still very easy for new players to get a hang of quickly. I’ve had tons of fun with it.
Out of these, Monopoly. But there's this really cute game called Rainbow Land that I used to play with my family during Thanksgiving that brings back a lot of Nostalgia. It's good for younger kids that want to play games together without it getting competitive.
