No one could tell me so I went and bought it since it's on sale. So had been wondering if The Last Campfire was DRM Free. I think I have discovered a new form of DRM on the Epic store. As for Epic, if millions of people bought games, downloaded then refunded, I'm pretty sure they wouldn't simply ignore it and freezing accounts is certainly one option.
Fortunately that hasn't happened yet and hopefully it won't either.
Hopefully it won't become a problem here, but if it does I can see them freezing the ability to at least purchase new games on accounts, (and as GOG said when they introduced the 'no quibble' refund from the earlier 'only if you haven't downloaded it'), they'll keep an eye on it and can easily revert back if it gets abused. Several games devs have also said they would actually rather nefarious people torrent games than buy illegal Steam keys for the same reason.
No specific examples, though it costs the store (and developers) far more to deal with abusive refunds than direct piracy. MarkoH01: Have you ever heard of GOG closing an account just because some user used their refund option too often? I know that they decide on a case by case basis if they will refund the game in the end but it is the first time I heard that they actually closed an account because of overuse of the refund option.
