Five Star Gift Ideas

How about getting him some Team Fortress 2 merchandise? There are plenty of options available online such as t-shirts, posters, figurines, mugs, and more. You can even search for some rare items or limited edition collectibles to make the gift more special. Another idea could be creating a personalized Team Fortress 2-themed gift basket including items like energy drinks, snacks, playing cards or other gaming related items. Finally, if your husband doesn't already have them, consider getting him the game's collector's edition or expansion packs.

Or you can get him a star map with the date when he was born.

Burcin Dalkanat says about Under Lucky Stars star maps:

“It was such a sentimental and romantic present for my husband's birthday (since he is so into astronomy and the moon on the background). The order came super well packaged, and now it is the gem in the basement :)”
