I don't want to share my ps4 controllers with my brother
What is your reason for not wanting to share?
I don't want him play the game that I' ve played.
You should share sometimes with your brother. It's wrong not to share things with a sibling like your PS4 controller.
Deal with it, I won't share my controllers.
I would assume that it would really make your brother happy to be able to play the game. If you fear him harming your controller than that may make sense, but if you do not want him to play just for no reason than it really comes across as pretty rude.
