my brother is obsessed

Well, talk to him, and threaten to uninstall his game. Try to input limits to him, otherwise
it's going to get out of control, and very very fast. If possible, talk to your mom too
so she can help you. Make him interact, and when possible, take him to a ride.
Cheers and good luck.

Install a hacked client and hack on every server he loves and gets him banned as fast as possible, that's what I did.

I'm not sure if this is the case, try playing another game or not.

Give him a motivation to not play it anymore, is their anything he likes better, I find this not only better and more effective, but it also makes them happier than brute force and limitation methods.

one time i was a child watcher i scared a Boy i was Guarding one night if i keep playing Minecraft a enderman will come and Take Him


(I'm a evil Child watcher)

tell him to watch movies , that's better than playing games i think

Let him keep playing, I was obsessed with it then i grew up and thought why do i play the game, Just let him play it for now and you'll see

my nieces and nephews play this game quite a bit but i just let them do that because everyone goes thru that phase where you just want to play video games all day.... and they have good grades so.

make him get bored of the game. That should do it..
