Right now, he's using games as trash compactor. An emotional void where he throws himself as a form of escape. It will work less and less over time.
It's healthier to find a more constructive hobby and spend the money he uses on games there. But he has to want it and find the will to go through it.
If he reached the point of feeling an obligation towards those games, then it's time to start distancing himself from them. Because they're the easier choice and complacency.
Instead of a subscription, loot boxes or daily checkpoints, take the money and use it for a course teaching a trade he feels attracted to. It will help him way much more in the long run.
Alternatively, start playing games with him and beat his ass.
Hot, getting hotter. Bad news are spilling over from their relevant communities. Also, a water shortage looms in the background.
Overall, my pessimism is growing enthusiastically this week.
