I dunno, I pretty much agree with Llyranor, worshipping old games for their own sake is pretty sad. Sure, Xcom (for example) was a great game, and still is, but whine whine, why won't someone make a new Xcom, they don't make them like they used to, wah wah wah is laughable.
Don't get me wrong, I loved PST, and that's an understatment, it's my favorate peice of storytelling in any medium, and not for being 'just a game' but because in being a game it was able to bring to life a story that was powerful to begin with. Likewise, Giants, Hostile Waters, Sacrifice and Battlezone 2 are 4 of my favorate games, all from 'the good old days' and all pretty much finantial failures, while my current favorate game, Hearts of Iron 2, is hot of the shelf, and simply doesn't try to be more than it is.
What i'm saying is that there WERE 'good old days' for computer games, and they were days before console crap meant that anything that didn't appeal to the masses failed because on production values it had to compete with things that did appeal to the masses, and in the days before people really got obsessed with graphics and other such completely superficial things.
Look at the new Relic RTS, they're praised on the innovation on being able to blow things up! WOW! You could do that in Z 10 years ago. In fact, in terms of innovation, a game like Z blows most modern examples of it's own genre right out of the water. Likewise, Warzone 2100 by the now dead pumkin studios.
What i'm saying is that there WAS a 'golden age' of games, but only by vertue of modern games being more and more watered down with mainstream crap with, inevitably, caters to the lowest common denominator. However, nothing has really changed, either these games didn't sell, or are so old that nobody even cares, so the only real differance is that market types have realised that if they are going to invest, it's going to be in what's already proven.
Either way, clinging onto substandard antiquities is laughable at best.
