It sounds like you are interested in games to be less interested you need to fill it with something of equal interest, or at least have general interest to start with.
Sit down and list the things that are of interest, you listed a few items but if you are just running at them in the hope they will pass the time then that's not really the same thing and so you need to think about your interests a little more, that done you will probably forget games quite easily since you will fill up the time with other interests.
I used to play WoW in almost every waking moment outside of my job and friends/drinking time.
Last summer I just stopped drinking which broke a bit of a habit, I just stopped WoW, didn't even log on to a PC. Bought myself a bunch of books, started sleeping better and towards winter started the drinking again.
Right now I've got a bunch of beers and Cataclysm that the missus bought for my birthday sitting right next to me in shrink wrap since 2 days after release and I've no intention of opening it at all even though I know it's there and even although still subscribed all this time. I'm pretty content just browsing forums and listening to music.
As mentioned previously, it's just habit, you are asking about a rush like BF but really that's just habit too. Break the habit if that's what you want to do, buy a box set of DVD's anything really.
That said, I found Halo for PC last night and going back to it after many years was great

. Not what you want to hear but everything in moderation.
Good luck, happy new year.
