Thanks for the link Disappointment, that was an interesting read!
All I will say, that we are lacking in the 'behind the scenes' parts of gaming while we get better at the 'stage show', and it's killing PC gaming.
By behind the scenes, I mean AI, story telling, characterization. Some of the things that would have improved much more drastically if the media had been kinder to text parser technology and the adventure game genre.
The stage show, is of course, the graphics, animations and sounds, which are getting better, not polygons and pixels, but art and level design, lip synching, etc. It general though, because we have little respect for what goes on 'backstage', we get shallow, great looking characters and we get worlds that look brilliant but are devoid of 'presence'
Some games, very rarely 'get it'. STALKER 'got it', Planescape Torment 'got it'. But mostly we get easily defined 'Hollywood Games'. The Supreme Commanders and Bioshock's are seen as hit titles, but even they are quite 'formulaic' in their approach. While we consider games likes STALKER and Planescape Torment and other titles as 'small sellers' I believe, when taken over the long haul, they do a lot better. Bioshock will probably stop selling long before Planescape Torment stops selling, even if we just talk about budget label sales!
Ebay can be a good research tool in this regard. With five year old 'hit' game selling for 0.99p on a 'Buy Now' and another one with bids at £12.87 with two days to go! Investigate ebay and you find out which games truly are the classics!
It's the proof that retro gaming on PC is in a growth spurt at the moment, with 10+ year old games going for quite high amounts, considering the age of the game! Of course, DOSBox has something to do with this, making old DOS games easier to install and play than some modern games!
