How about giving him a personalized Sims-style character drawing or painting of the two of you together? You could hire a portrait artist to create it, or you can create your own using Sims-style character creation tools online. Another gift idea could be a special edition of The Sims game that features a storyline or items that are unique to your relationship. You could also surprise him with tickets to a Sims-themed convention or event.
Or you can get him a star map with the date of your anniversary.
