Addictive - Yup!
But for me money is more addictive (as in perserving mine). I budget for what I can afford and stick to it no matter what. Yes, I actually have a budget for this activity. I am still sampling the "elite" before I settle down to my ultimate top 5-6 to rotate amongst.
Young and single helps. When I marry "the one" I can definitely give up the hobby, for her and the money factor.
