Ehhhh, the grass is always greener, and nostalgia is a hell of a drug........
Some games may have gone backwards, but gaming as a whole is in such a good place right now. Go look at a GOTY thread and start making a list of how many amazing games have come out this year. My backlog of recent must play games is insane, and getting longer every day. I also think that when people go back and play some of theses older games they will realize how hard it is to play them. Just because it was the best thing ever 20 years ago doesn't mean the gameplay is going to hold up today.
