p.s today i hit him and bust his lip

Tell him to either actually try some of the games on the system or to shut up and go play his PS4 with the games that your PC could totally do better, anyways.

Don't repost a thread that a mod locked and I don't think this is a topic for here.

I've decided that, as @Tasuki said, this isn't really a topic for here.
