I think it's happened to us all at some point or another: a game you've idolized from afar finally comes out. You boot it up and brace yourself for magic. Hours pass. Magic still hasn't happened. This is... unexpected. That is when you begin your Dante-esque multi-stage descent into a very unique sort of madness: disappointment.
There are some classic PC games -- some old enough to buy their own alcohol -- that are as good today as the day they were released. You may not have heard of all of them. After all, when a game has been out for a while, people generally stop talking about it. They are still out there though, waiting patiently for someone to pick them up and play.
