Answer:
You should go take a few minutes to calm down in your room. Just take a few minutes and think about what you are going to say. Maybe try to explain to them about the games helping you in a different kind of way. See if you can make an arrangement with them, a negotiation. For example, if you do something for an entire week to their satisfaction, you can have it back for at least an hour every day, or you can have it 3 hours on Saturday, etc. You have to take baby steps though, and show them that you can handle whatever they give you in the sense of how much time they might give you for example. I know that it may be hard to control your anger, just see if you can ease into a negotiation convo with them and see how it goes. If they still say no, then try not to get to mad because maybe they will come around. Especially if you make a good suggestion. But then again, it all depends on you and your parents, i make no promises.
