I would say gaming in my case. I can spend inordinately long periods of time playing games! Video games mostly at this point in time. I can spend days at a time playing Civilization for example. I also find the lure of competitive gaming to be quite large. I played Starcraft competitively as a youth & am looking at getting back into playing certain games more competitively. I'd avoided multi-player games over the years until recently due to my tendency to be overly competitive. I find some gaming to be much akin to gambling as in some cases the risk to reward ratio for various events ends up being basically a gamble. At the moment my game of choice is Magic: The Gathering. I'm playing on the MTG: Arena client & find it quite addictive to me. I spent a good chunk of time this week racing to Mythic for a website contest. I managed to not only succeed at being one of the first 10 to Mythic in the contest but ended up in the top 50 ladder ranks overall! Considering it was my first time trying & basically my first time hitting Mythic as well I was super surprised to have done as well as I did & am super happy about it. Totally did not expect to succeed on my first try let alone rank so high overall.
I really enjoy the feeling of setting my mind to something & accomplishing it. I guess I could call that an addiction to the high that comes from 'winning' or success. Other than that I am pretty bad about binge watching entertainment. Anime in particular I find myself getting hooked on & watching through. I'll throw that on the list as my wife seems to think it should be. That's another thing I spend a great amount of time on. Big fan of anime. That's the first things that pop to mind when I think of things that might qualify as "addictions" though I'm sure I have plenty more.
