Specifically for video games, I actually think abstinence is much more achievable than moderation, because if you haven't installed the game yet you can't get any instant gratification. In a moment of weakness you might click install in Steam, but then 20 minutes later it's still downloading and you aren't having fun yet and maybe you come to your senses and cancel the download. You could even uninstall Steam to make it more difficult for yourself.

If it's already there ready to play, it's incredibly difficult to limit yourself to a certain time period (if you're addicted). Endless instant gratification, zero friction, the game never gives you an opportunity to pull yourself out of it.
