HijacK: Gaming was OK with used sales when games didn't cost so much money and effort to be created. The wheels have turned. Games now have budgets of hundreds of millions of dollars ,and publishers and devs have something against used sales.
Hmm, just the other day I read some gaming article (from 2012) about the biggest fallacies about the gaming market. They specifically mentioned also "used games market destroys the profits of gaming companies" and "game development costs have skyrocketed".
I personally am not really craving back to second-hand market to PC gaming, mainly because that is very incompatible with DRM/copy protection-free gaming. I rather have DRM-free gaming than the ability to sell/buy used games (with DRM and/or copy protection). And PC game prices have eroded so heavily anyway for various reasons that I wouldn't even see the point of trying to sell my older games away, or hunt for second-hand copies.
But for the development costs, the article mainly pointed out that while some costs of game development have risen, some have plummeted, e.g. regarding development tools. They gave as an example that e,g, the development costs of Shenmue (the original 1999 Dreamcast title) were quite a bit higher than most AAA-titles made today, especially considering it wasn't a multi-platform release, but only for one console.
Googling for some data, Shenmue apparently costs $70 million to make (for just the Dreamcast version), while e.g. GTA IV, which is touted as one of the most expensive games ever made (as of at least 2012), cost $100 million (and I presume that means all the platforms it was made for, at least initially).
And also it was pointed out that the development costs fluctuate a lot anyway, e.g. when a new gaming engine is introduced, the costs are much higher than subsequent games using the same engine.
I really should try to find that article, I ended up there from some gaming link in these GOG forum discussions, which had a link to that... I didn't fully agree with that article though, but I felt there were some good points there, and some data to support it too.
