I started with games that don't have an ending but realized I didn't personally have the self control to stick to it. Especially with a small child every minute is precious and I'm not going to get to have all these "firsts" again. This was really, really tough though. Maybe when I'm older with more free time I'll jump back into video games, I bet they'll be super cool and even more addictive by then.
At least now I accept that I don't have to finish games. That it's ok to even uninstall one after a couple of hours of play if they don't bring me any more joy.
Also, there needs to be a category of game guides for those of us who prefer small quality gaming experiences over fillers.
I'd suggest if you're really dreading games so much, try giving them up for 3 weeks. That's about how long it took me to stop freaking out that I wasn't spending every waking moment playing Diablo 3 or literally ANY game. I felt really awful. It really surprised me how negative my initial reaction was, but lately I've been finding myself reading books for pleasure again, and I'm going out with my family more often. I realized I was implicitly choosing video games over spending time in the real world with actual people.
Addictive open ended games, sandboxes and competitive online games quickly lead to severe existential depression so I just don't play them. Sometimes people ask me to join them on MMOs. I have to refuse.
But yeah. Board games are the best way to free yourself from screen addiction, in my opinion. And there's tons of interesting board games out there nowadays.
And if we're including things like D&D and Pathfinder, that's easily months of entertainment.
