^This is a good tactic: putting your money to work so you become independent from "the man."
I will say that it is likely difficult to save money with a video game addiction. So many of the games are endorphin boosters and pay-to-play now . . . anyone could get hooked and quickly be pouring more money than they have into the streaming game black hole. It's a way to have attainable daily or weekly goals auto-set for you by the game and makes your brain feel like you are successful and making progress each day. It feels like an accomplishment to reach the goals set by the game, and for many people it is a needed escape from other stressors. I've watched older relatives pour their life savings into Candy Crush (no joke), and the younger ones wipe out every brown penny with games like Fortnite, CoD, and NBA 2K. I've got nothing against these games, which can be quite fun: but beware, don't get addicted!
Here is one of the best videos I've seen about coping with it:

He has a lot of self-reliant messaging that appeals to young men. Fix your own car, learn to do some construction trades, 50 ways to earn good money without a college degree, etc. I mean the dude painted the peeling roof of an old van that he bought with flat black paint and a paint brush! There are also some military vets who have posted a lot on the boards (like
@Nords who wrote a book about turning military pensions into much bigger stashes.)
Finally, I have a brother who doesn't trust the stock market. He got burned very early on in life with a predatory advisor. He doesn't trust the stock market, and he hasn't saved a cash stash for retirement. What he has been willing to do recently is start putting money in money markets (like VMFXX and SPAXX.) Long term these aren't the greatest investments, but at the moment they are yielding 5+%, which is certainly better than a poke in the eye. It gives him a place to stash cash while he gets comfortable with holding money at places like Vanguard and Fidelity. Once he has a decent pile going I will suggest putting a "bucket" on the money into stocks long, but not right now (he's not ready and there are indeed lots of indicators of a looming recession.)
So, you could rave about that more conservative option for putting money in a Roth IRA . . . YOU NEVER HAVE TO PAY TAX ON THAT MONEY AGAIN! That might appeal to your brothers. I sure wish someone had repeatedly shoved the Roth IRA message down my throat when I was in my 20's.
