An interesting thing to do to judge what people think of different games is too look at the GameStop trade value.
For example, I compared the trade value of original Assassin's Creed for PS3 to Resident Evil 2 for PSOne. In both cases, I'm looking at the "Greatest Hits" edition to parse out any added value they might have as collectors items for certain people. Both games were extremely popular, sold millions of copies, and neither is particularly hard to find.
GameStop will give you $1 for Assassin's Creed and $2.50 for Resident Evil 2.
The marketplace values the game running at 240p with tank controls and pre-rendered backgrounds over the 720p game with more modern game play.
People buy ("prefer") newer games over older games because they're newer and they offer newer things. After a couple of years goes by and the dust settles though, I think you can make a more objective valuation.
