How can you become unaddicted to computer games

Hello, I am addicted to some computer games. I can't seem to get unaddicted except for one of the games. I want to delete my account on it but also want to keep it. I can stand without it for a week (no wifi at holiday place). I don't know why but I play it everyday 1 or 2 hours (not too bad right?). I DO NOT KNOW WHY I'M ADDICTED TO BE HONEST?! I KEEP PLAYING THE SAME GAME WITH SAME MAPS AND STUFF OVER AND OVER AGAIN EVEN THOUGH I MAXED OUT ALL GEAR. I badly want to be unattached to my laptop and focus on my studies because playing video games leads you nowhere, not to a university just nowhere. Please don't say: Became unaddicted that won't help. I am spending 10 minutes writing this. I have no idea why I am even addicted to it. But like I said before I don't want to delete my account. Should I maybe make a sort of timetable and only play these games in the weekends or 15 minutes at the latest? Does anyone have the same problem or thing going on? Any advice? I have some ideas. #1 I sit inside the computer room in my house with parents supervising so I can't be tempted. #2 Completely delete all my accounts and stuff on addictive games (next to impossible slightly possible). #3 Play few hours on weekends or at maximum 15 minutes games daily. #4 Abandon addictive games (next to impossible but slightly possible I'd rather delete accounts this is practically MISSION IMPOSSIBLE). Any tips or more ideas?
