Timboli: Some good points
Most people never think ahead of the tip of their own nose. They only see
"the right to re-sell your downloaded pc games" and already see themselves "rolling in the dough".
What they don't see, is how that would affect a DRM-free store like GOG, or how low they would have to go with their resale prices, to even have a chance to sell on the swamped market.
And even if we leave the DRM-free part completely out - the only halfway realistic possibility to get a "worthwile"
(= questionable term, since you'll ALWAYS sell at a loss) amount of money back?
You have to buy at full price, then play through the game immediately, to sell it as fast as you can again, hoping that thousands of others who do the same, aren't undercutting your "entirely sprung from wishful thinking" resale price.
So, you better be very quick and don't set your expectations too high.
And a game that's "10 years or so" old?
Worth Pennies. At best.
And it probably sits unused on a few hundred thousand accounts, that also want to get rid of it.
Lot of competition.
Ever sold one of these Steam collectibles?
And with common games, we're not talking about something "rare" and "highly seeked for".
And finally, your point:
"
It might be nice for customers, but it would hugely impact the industry negatively, and so in the end impact customers that way too."
Bingo!
Because I can tell you already what the immediate effects of such a right would be: higher prices.
Every game that gets re-sold this way, is a potential sales loss for the companies.
And a "x-fold loss" one, since there's no limit to how often the same copy of a game can be re-sold.
So, customer A pays the dev/publisher once the price for "copy 1" of "game X", then re-sells it to customer B, who does not pay the dev/publisher, but re-sells it again to customer C, who does not pay the dev/publisher, but instead re-sells it to customer D, who does not pay...oh yeah...I can totally see, how much the devs/publishers would love that.
But hey...maybe I don't understand jack shit of business...maybe the devs/publishers will lower their prices, instead?
You know - to undercut any eventual re-sales.
To make the effort of re-selling "not worth it" anymore.
Could be...I know for sure, that that's the wet dream of some here.
Of course...such a right could also lead to the closure of many games companies...
Whatever...like I said:
most people never think ahead of the tip of their own nose.
