Bf plays video games all day long I’m so annoyed

Very simple situation. We live in a flat together, just us. All he does is play video games or watch streams all day. If I ask him to clean or cook, or to go out for a walk, he does all those things. However, if I don't, he'll just spend all day (or days) playing video games or watching other people play video games. I'm not exaggerating, he literally does nothing else.

I don't think I can tell him to stop playing video games because it's his only hobby and who am I to tell him what to do. What should I do?
