Tell them you'd want to chat to them about anything and that you'd like to locate the ideal time for them. They will appreciate it if you respect their time and do not bombard them with arguments. Choose a suitable time to question them, and don't ask them shortly after they get home from work. If you're afraid of losing access to social events such as movies or games, then just tell your parents that you'd like to quit playing video games and show them the example of other people who have done so successfully. Explain to them that gaming is important to you but that you need to focus on other things too. Tell them that you'll still visit when you can but that you want to cut back on the frequency of these visits. Finally, give them time and space to understand what has changed before you ask them for permission to quit. It's best to address this topic face-to-face rather than by email. This way there are no misunderstandings and you can come up with a solution that works for both of you. If you send an email then you are making assumptions about how they will perceive your message and may even come off as accusatory. You should also remember that whatever you decide, they loved you enough to let you make your own decisions when you were younger and you should never be made to feel guilty for wanting to grow up.
