That's a great interest to work with! Here are some board game-related gift ideas:
1. A board game he doesn't have yet: You could do some research to find out what board games your grandpa doesn't have and get him one of those. BoardGameGeek.com is a good resource for finding new games and seeing user reviews.
2. A custom game storage solution: If your grandpa has a lot of board games, he might appreciate a custom storage solution to keep them all organized. You could either buy something off-the-shelf or look into hiring a carpenter to make something custom.
3. Board game-inspired artwork: Depending on your grandpa's style, he might appreciate some artwork inspired by his favorite board games. Check out websites like Etsy for unique and interesting artwork options.
4. A subscription to a board game magazine: There are several magazines dedicated to the world of board games. A subscription to one of those would be a gift that keeps on giving throughout the year.
5. A day at a board game cafe: Depending on where you live, there might be a board game cafe nearby where you can spend a day playing board games and eating good food. This could be a fun and memorable gift for your grandpa.
Or you can get him a star map with the date when he was born.
