Escapism is one reason adults play. There's a stigma with video games though. Leave work at the end of the day & say you're going to go home & watch movies tonight & nobody says anything. They'll probably ask - "which movie?" But say, "I'm going to go home & play video games" & it's a completely different response.
I think video games are better than movies though because you have to be more engaged & actually participate. You have to listen to stories & respond or remember tips given earlier in the plot. Games involve creativity, problem solving, reflexes, hand eye coordination, patience, self-control etc. Then there's all the benefits research is starting to show - cognitive, creativity, motivation, emotional, & social benefits. I plan on playing video games with my daughter & son when they're older. I think it'd be a good father-son/daughter, co-engagement activity. It's better than all the parents who let their kids play video games & have zero idea what kind of games they're playing or how much. It shows your kids that you're interested in their interests. That is, if my kids will be interested in video games of course.
Video games are turning into even more of an art. Story telling is better than ever. Music & soundtracks are becoming epic. My wife & I regularly listen to podcasts (Kotaku) about video games in the car, & they're fascinating. The interviews with the developers, writers etc about the creation process is pretty eye opening. The industry and creation process is much more interesting to me than TV, music, Film etc. There's a so many layers with video games that people don't realize.
