There's definitely SOME escapism in gaming, but that's also why I read and watch movies. That said, all those things are designated for evenings after I've done everything else (well, except for reading, I kind of have a reading problem).
When I say "immersive" here I mean I've spent enough time in the game for it to be interesting. If I'm done with the game in a few hours... eh. Just not my thing. And that includes big titles. I hated God of War 3 because it was over in a few days and I had absolutely no desire to replay it. I loved the first The Force Unleashed because even though it was short-ish, it was fun to play over and over. I didn't like the second one because it was shorter and just annoying!
I recently was pretty damn bored and confined to the house due to illness so I did try some indy games recommended by friends - friends I met while gaming, I might add, so I figured I can trust their taste. I played Lifeless Planet, which has a lot of positive reviews. And it's very pretty. But it was basically a platform-jumping game which was just annoying, and the story... the story made no sense. $20 for something I was done with in two days and never want to play again.
I'm also playing Life is Strange. The story in that one is... so far, a bit better, but the game itself stresses me out and I can't connect to any of the characters.
Compare that to a Skyrim. I'm still playing that thing. In fact when I moved to PC I ended up rebuying it - mods make it virtually infinitely replayable.
I'm not just saying "no" without ever trying something. It's just not the kind of thing I like.
