The games distribution platform GOG updated its refund policy today, expanding it to a flat 30-day refund period. This even applies to games that have been played, though GOG has stated it retains the right to review individual refund requests and deny them should it find a reason to.

This is quite generous move from GOG. However, this kind of generosity might be misused by many. Since, all GOG games are DRM-free, people can just buy, take the DRM-free files from the game, then ask for refund. Of course they're not eligible for game further updates, but still, this might scare many game developers.
Sounds too generous, but this mainly applies to games that aren't already pirated, which should be few.
It could scare away devs, but GOG could just reverse the policy. They're trying to strike a balance between devs getting their due but also for consumers that either don't like the game or find it's buggy/incompatible/etc.
I see GOG canning this policy quickly if any devs threaten to leave over policy abuse.
I remember when EB/Gamestop had the policy for PC games. I only ever used it once because a game was really bad and buggy.
