Your brother's probably 15 I'd guess?

In reality, its highly doubtful that you can do anything to stop his addiction. Alone anyways.

Your parents are obviously spoiling him, and aren't being a help, which of course severely lowers your chances of doing anything productive. In reality you don't need to confront him, but confront your parents, you have to make them realize that it's a problem. There's no point to confront him if he just has to go to your parents.

If nothing works out, I agree with Vexx's suggestion, you need some third party help. Don't feel that you have to be your brother's savior. That's your parent's responsibility, and you ought to make them realize that.

But for now just screw his game / internet to control him for now. If he confront you w/ parents that's probably the easiest way to get everyone together. Whether or not it'll become a flame war is really dependent on your parents.

EDIT: Also Saintless you're a crazy crazy person.
