Brother does nothing but play games and collect anime figures after work

Problem/goal: brother is 40 but prefers to stay at home and play games/collect anime figures

Context: So disclaimer lang. My brother has a good job, has his own condo and car. He goes to the gym four times a week and controls his meals. He's in a better financial position and is more physically fit than I am.

But when he gets home, all he does is logon to his computer or PS5 and play video games. He also has what I think are an unhealthy amount of ecchi/hentai anime figures. I've heard him been called "not boyfriend/husband material" because of his hobbies. He has friends but they all share the same hobbies as him. Aside from that wala siyang social life and I'm worried about him in the future.

Previous attempts: none. I don't even know if I should intervene.
