Looking into it, ZOOM Platform is run by the Jordan Freeman Group, which has a similar mission statement to GOG, that being a DRM-free games platform that also touches up and sells old games. They seem to have acquired publishing rights to the FlatOut trilogy, along with either source code or enough resources to touch them up without it. I didn’t know about them until this post, so it’s nice to see that GOG isn’t the only DRM-free old-games platform around.
Webtoon is still shitty in other ways. When they adapt a property, they want it their way, regardless of the author’s original vision. I’ve seen several stories that originated on Royal Road get Webtoon adaptations, and the adaptations always seem to change or leave out important parts of the story, making characters look stupid or just completely replacing entire sets of characters, forcing the story to diverge substantially when inevitably something they got rid of turns out to have been critically important to where the author was taking things. They turn great stories into middling slop every single time.
