I feel like this as well. Modern games are not deep enough, I still want to be thinking about them hours after I turned off the console: the worlds they made, how I could improve to get past a certain part. I haven't bought a videogame in a year and haven't seriously enjoyed one since Metroid Prime 2.
The only game I still put time into is Starcraft II and that's because I can always improve and I watch the pros play like a sport for money, so I can try out their build orders in my own games.
As far as I'm concerned Nintendo is dead and no other company puts as much polish into their games.
