There are many games that will give you much longer than 20 hours. It's actually a complaint by some about modern open world games and how they're geared towards 40+ hours for even a basic completion. Longer if the player wants to finish some of the side quests. And then that's not counting mods and how those extend game time even further. And also not counting all those open-ended games which last as long as you're interested. Gaming is in very good shape right now. I think most of the lack of immersion comes down to age. And also comes down to having many more diversions when you have an afternoon to yourself with time to play.
