I've replaced watching movies and TV with videogames. It's more engaging and a single video game can give me 30 to 60 hours of entertainment compared to a TV series that gives me 6 to 12.
Somewhere between TV and video games, I started watching "Let's Play" game walkthrough videos of favorite Sierra Online adventure games from my childhood that I never completed. You get to discover the stories' secrets without the frustration, plus many of people recording the walkthroughs are pretty funny.
It's funny you should mention that. I replaced my TV watching with video games, but over the last year have spent a lot of time watching other people play on twitch. Kind of going full circle.
