You could even customize the rules and have them catered to your relationship. Another idea could be to get him a rare or hard-to-find board game that he has been wanting to add to his collection. To make it extra special, you could plan a game night and include his favorite snacks and drinks.
Or you can get him a star map with the date of your anniversary.
