If we’re talking actual legit addiction, to the point of finding it hard to quit, Skyrim and Pokémon (first four generations). Any other game, no matter how much I love it or how many hours I’ve got, I could put away and not touch for a while. When I first got into Skyrim, I played it nonstop for about 3 or 4 years, hours a day every day. After around 5k hours I finally had a hard drive failure which corrupted a save file and I finally took that as a sign to stop playing. I actually stopped playing video games entirely for a while to make sure I didn’t go back to it. About a year ago I figured I’d reinstall it and play again for a bit, immediately sank 50 hours in and uninstalled it before I fell into that rabbit hole again.

Pokemon is similar, though not as bad. But any time I revisit a Pokemon game I have to go through all the games in the first four gens, get super into it with dozens of tabs on individual Pokemon and stats and such, and then I have to stop myself, otherwise I’d probably do the same thing as Skyrim. As a kid growing up I was properly addicted to that series, and as an adult it still hasn’t gone away.

There’s lots of other games I’ve had tons and tons of hours into, but I could hang them up and move on. Skyrim especially but Pokemon too are actual addictions for me.
