I used to take part in marathon D&D sessions over the course of a weekend, where we'd play non-stop from Friday night at midnight, until Sunday lunchtime, breaks for the loo and to collect delivery food orders from the front door once a day, but that's it. I doubt it qualifies as an addiction, we'd only do it once a month or so but it was pretty intense.
