I know that you are addicted to computer games, but addiction to games are like ecstasy. You will not be able to stop the addiction once you stop. Playing educative games can help sometimes, but games are still overall bad, because educational games are not really interesting, and when you play non-educational games, you tend to waste a lot of time. All this wasted time can be spent for better purposes, like doing homework, etc. It will benefit you a lot more than playing games. I hope that you can kick the habit.
