I agree that newer games are much more polished and that older games offere much more variaty, that's true. My main problem with the newer games is the lack of ganras I like, RTS games, turn based tactical and strategy games and more. Those are the ones lacking, also complex RPG games.
We do have some interesting newer games recently, but they are few and far between, this is why I like older games, but I do play newer ones as well.
