Five Star Gift Ideas

Great! There are a few different gift ideas I can suggest based on his love for Half-Life 2:

1. Half-Life 2 poster: Find a high-quality poster of graphics or artwork from the game that he can hang up in his room or office.

2. A Half-Life 2 t-shirt: If your boyfriend is a fan of Half-Life 2, he would definitely appreciate a t-shirt featuring a design or image from the game.

3. Steam Gift Card: You can gift him a Steam gift card so that he can purchase the Half-Life 2 game if he hasn't played it yet, or purchase in-game items if he already owns it.

4. A figurine: Get him a figurine of his favorite Half-Life 2 character, this can be a good desk decoration for him and would remind him of his love for the game.

5. Half-life 2 artbook: If he really enjoys the visual elements of the game, then he might appreciate an art book filled with concept art and design sketches from the game’s development.

I hope these suggestions are helpful in finding the perfect anniversary gift for your boyfriend.

Or you can get him a star map with the date of your anniversary.
