How about getting him a paintball gun or gear such as a mask, gloves, and chest protector so he can have his own equipment for paintballing? If he already has his own gear, you could get him a gift certificate for more paintballing sessions, or even arrange for a group outing with his friends to a paintball park. Another idea could be to surprise him with a new paintball arena or obstacle course set up in your backyard or at a nearby park for him and his friends to play on.
Or you can get him a star map with the date when he was born.
