Then message support that the situation of the game changed and you are now unable to play it after an update. Unless you are in a lawless country that eill essentially force their hand in giving you a refund
Yeah I’m not sure where you’re getting this from. Digital “ownership” has always been a hot mess, because you purchase the right to play the game on the publishers terms.
Ethically Steam should provide a refund, legally I can’t find any evidence that they are compelled to.
They are not compelled to but Valve have generally been really good about providing refunds, even outside of the “contractual” window, if you point out there is a good reason.
I got a refund for mordhau with like 30 hours in by just linking to the pc gamer (?) article about the rampant anti-semitism and racism and “I would rather not give money to literal nazis”.
