I've spent approximately 3 hours a day on video games for a year now. What should I do to break this habit and what are the possible after-effects of this?

I’ve been terribly bored for a while now. I decided that I would find a hobby, so I chose a video game to entertain me (not so much a hobby, I know.) I’m scared that the possible effects of my bad habit will effect me in the long run. I’m looking for a new hobby at the moment, but I’m just so darn lazy…. How can i turn this around?
