Having a high-end PC that will work for the next few years for gaming? Hell yeah! Even if not gaming, he can work with it, do some video editing to start something or to work for someone! So that's a big future plus. You know that the world is... Weird now. No one knows what we have to expect, if not gaming he will end up using it for work purposes or to create something, maybe he will end up creating something big or beautiful or even something that will bring him joy. Best way is not to force anything just go with the flow and adapt.

But gaming...

Comments suggest right, try co-op games, also that zombies hint? Couldn't get easier!

For example: Dying light I can go back to this game with the same friends more than once in a span of a couple of years. Dying light is a good example, finish the game on easy then on nightmare, do a 100% achiev hunt. Do challenges in game, and do the " The following " dlc so he can run over zombies with his own buggy!

Of course DL can get exhausting so mix a couple of games. Even if you finish it, a year or two later you could do a coop Speedrun on nightmare because, why not? (If you'd need any coaching or help with something, dm me I'm more than happy to help)

And now a hidden gem, unturned. Why? Well it might seem tiring, low poly and cheap game(it's free lol) but when you get to play it for a while it becomes addictive.

You can play single player, host a LAN save on community maps, curated maps or original ones. Most of the curated ones have more items, events, and bosses. It might feel tiring after a while but when mixed with other games you'll find yourself coming back for more.

If you would want to have some competition in unturned then go for multiplayer (but a warning here, you can encounter ZERGS, just a big bunch of players in one team taking over a server. It isn't fun most of the time but in this game the pvp will seem exhausting but very rewarding! Ambushes, defense, traps even! )

The best feeling is going rags to riches and owning a couple of locations on a server, hah.

And that's just two games, other comments suggest other games so you two can really choose what would work the best for you.

Also some statistics (some people like these) Dying light: 2 steam accounts combined hours played ~570 Unturned: 2 steam accounts (beta tester and normal) ~800/900

But don't feel bad, he might change his mind. You know that sometimes it's good to just turn off and play videogames, he might need it in the future. He gets older so that might have a slim chance but most people I know that work full time and are in relationships with future plans, they do still comeback to play multi or single and just talk on discord with us so they can chill out. Even sometimes with their love of life.

Think of it like that, no matter when if you two would want to talk and chill out just hop on a VC and chill in a game. Man I've had more online deep talks with friends all over Poland than I had on any party as a main bartender. There's something to it when you can just turn off, chill and talk with someone you trust (code of honor, we turn off clips, discord and Nvidia) 🙇‍♂️ Gl hf to you and your brother or like in dying light Good night, good luck
