To be fair here, the Movie Industry and the Recording Industry BOTH want dib dollars on resells of those product. Car manufacturers get money from parts (even the off-brand ones).
That's true eventually, but pretty much everybody who buys a new car every year would not do so if there wasn't somebody buying the old one.
It is therefore reasonable to assume that a lot of people who regularly buy new games do so using money from sales of their old ones; without those used-game sales, they would not buy as many new games.
The result is that forcing people to only buy new games will result in them buying less games, which will push the price of games up (reducing sales numbers further). Used-game sales enable game companies to shift more units at their original high release price.
I think David Braben is wrong: used game purchases don't force game prices up - not by any significant amount - for the simple reason that those people generally wouldn't be buying the game at its high release price anyway. They will either wait for the price to drop or they won't buy it at all. I do suspect that removing people's ability to legitimately buy second-hand games will increase people's willingness to pirate them.
Didn't Valve release some stats about how game sales shot through the roof when the prices were dropped? Found it: Do video games cost too much?
I still call shenanigans.
Quite rightly... although it's been about 4 years since he posted anything here.
