Psyringe: Well, there are reasons to prefer Renaissance, and there are reasons to prefer the base game plus the Pirates expansion, but what reason would there be to prefer Venice? It's basically a texture mod that is 90% identical to the first game, and buggy in the few gameplay parts that it does add.
The real issue is that there's a publisher selling basically the same game three times to people who don't know how similar those games are. Cutting the by far least popular version out does look like "caring about the games they offer" to me.
Smannesman: GOG has plenty of bad games and has also sold broken games before.
Interstate '82 might even still be very broken, I haven't kept track.
GOG like any other store cares very little about quality and very much about money, so it's possible they're not selling it because they think it won't sell.
Well, I said that GOG cares about quality. I didn't say that they are always successful with their quality assessments or that there can't be other factors which may convince them to release a sub-par game.
We could, of course, shoot examples against each other now - you could cite Interstate or MoO3, I could cite the retraction of Dark Matter or the known rejections of numerous games. To me, when I look at the big picture, it seems pretty clear that GOG cares considerably more about quality than most other stores. On the other hand, it's really not that important to me that I would try to convince you if your opinion differs - feel free to disagree.
I just kind of wonder why we are discussing this? *scratches head*
