How about getting him a Mass Effect 3 collector's edition? It includes a SteelBook case, an art book, a lithograph, a digital soundtrack, a N7 patch, and exclusive in-game content codes. You could also consider getting him a Mass Effect 3 poster or a Mass Effect 3 action figure of his favorite character from the game. Another idea is to get him a video game-related T-shirt, hoodie, or hat with a Mass Effect 3 design. He would love any of these gifts, as they all show that you support his interests and appreciate the things that bring him happiness.
Or you can get him a star map with the date when he was born.
