I love having game night with just my hubby and me. We often play scrabble, as well as Trivial Pursuit. There are some other games out there that are along the same lines as scrabble (like upwords or boggle), so maybe that would be fun? There are games that are probably more fun as a crowd, but things like Pictionary, Yahtzee and Password can also be fun just one on one. (We also like to watch Family Feud and play along -- ha!)
