Only used games have minimal deprecation over the first 6 months ie the used game is worth 95% of its retail price. So the other retail models have been around longer but have much higher deprecation than the games and thus cannot be used as model.
Where are you getting this data from?
Maybe some of the AAA titles aren't depreciating all that much but the rest are. Fallout: New Vegas was 50% less than launch at 6 months, and that was arguably one of the better titles. Mass Effect 2 dropped like a rock in a similar time frame. And I've seen games that lose 70% in two weeks because no one buys it. And this is the new game's price.
We're talking about the amount you get for a game when you trade it in used because that is where the depreciation lies. Yes, a car loses thousands in value when you drive it off the lot but games lose a lot too. I have seen at most $40 dollars being paid (as trade-in never as cash) for a $60 game. Most of the time I see a new-release game within a week only getting $30 to $35 in trade-in because the early adopters got bored and decided not to keep the game around. Nowhere do I see $57 dollars being paid for a game that is $60 brand new.
