Any protections to consumers are a win. I think overall this will be a positive for gamers.
IMHO this ruling is shortsighted and pushes for a future with increased monitisation that isn’t in the box value of the game and targets to hurt the Devs that make consumer friendly games while giving games with loot boxes and microtransactions an advantage in the market when talking in terms of overall sales for the devs.
Your last paragraph could hold some truth if publishers think this will affect profits. I don’t know if this would significantly impact profits since we’re talking about a new secondary market that did not exist in the digital space before. There’s probably some historical data for how physical used game sales affect new game sales but it might be hard to quantify since that market has existed pretty much from the beginning.
I would anticipate another across the board price increase for games as a result, but I see this more as an excuse for greed on the publishers’ parts rather than a cost to offset any actual lost revenue.
Such a scum bag move by Sony that I have to buy another DS5 to play this with my daughter on PS5 when I have several perfectly good DS4s whose only purpose at this point is to occupy a landfill it seems.
