When you're hosting an anniversary party, Games that take the guests back in time and allow them to remember "the good old days" are excellent. Here are a concentrate of great Games:

"The Big Day" Anniversary Party Game
Anniversary party Games like this are sure to bring back memories of the big day - with a lot of laughs thrown in for good measure! Prior to the party, acquire together some old dresses, daggy jewellery and garters (fabric scraps will do) for the "brides" and shirts, pants and ties for the "grooms". Put the box of clothes down one end of the room, and acquire the guests at the other. Guests pair off (preferably male/female but it precisely doesn't matter), and one puts on a blindfold. The object of the game is for the blind-folded players to go to the other end of the room and put on their "wedding clothes" - but their partner can only guide them with verbal instructions. The partners then swap roles. The first concentrate to be dressed for their "wedding" are the winners of this anniversary party game.
