I do this now and them, most memorably for me with Batman: Arkham Asylum. I started it, played it for about 2 hours, then decided to play something else for a little bit. That little bit turned into a 2 month break. Started it again, played it again for 2 hours, and stopped at the exact same point in the game, then did the same thing - went off to play something else. It was only after I'd been bought Arkham City for my birthday, and had both sat on my shelf for months, that I forced myself to push through. I'm thankful I did, as I absolutely loved both games, and ended up completing them back to back without touching anything else in between.
