Spiders get bored, ya know.

Do not impinge on the Sanctity of a man's shed. Or a woman's shed, for that matter.

Why does your boyfriend feel the need to lie to you about this? If he's spending endless hours hiding away doing a hobby, why would you have been okay enough with tinkering, repairs, etc. but not gaming? I get that not everyone likes video games, but functionally, if he's not engaging with you for hours at a time while doing either activity, what material difference would it make? Wouldn't it be better to be able to have open and fair conversations about the balance of solo vs. partner activities period and come to an actual agreement? If there's a problem with how much time he's spending on hobbies vs. relationship stuff, focus on it like that. If you'd just rather he be "acceptably productive" in his downtime, perhaps interrogate why you feel that way and whether it's truly necessarily to never just have "fun" time?

That’s hilarious and reminds me of Hal from Malcom in the middle
