Five Star Gift Ideas

How about a Grand Theft Auto themed gift basket? You could include items such as:
1. A Grand Theft Auto video game (if he doesn't already have it)
2. A Grand Theft Auto poster
3. A Grand Theft Auto t-shirt
4. A Grand Theft Auto baseball cap
5. A Grand Theft Auto coffee mug
6. Grand Theft Auto keychains
7. A membership to a video game streaming service, like Twitch or YouTube gaming.

Alternatively, you could plan an outing for him that's Grand Theft Auto themed. For example, you could book him a driving experience day where he can learn to operate exotic cars like those in the game (e.g. Lamborghini, Ferrari, etc.) or take him to a go-karting track where he can pretend he's in the game.

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