How about this for a unique anniversary experience: arrange for you and your boyfriend to go to a laser tag arena together, where you can have a great time bonding and having fun. You could even make it more special by setting up a post-laser tag dinner or picnic where you can enjoy each other's company and reminisce about your time together. Additionally, you could get him a laser tag gun set with extra accessories like laser sights, tactical vests, and even a home laser tag set so that he can continue to enjoy this hobby even when you're not around.
Or you can get him a star map with the date of your anniversary.
