zeogold: The problem a lot of people have here is what GOG rejects rather than what they accept (if you rejected X, why is Y here?!). So really, the base problem isn't "I hate the new game here!", the problem is "I hate the fact that the game I wanted isn't here!"
Breja: This.
I know arguments about "GOG releases to much of X which I hate" arise quite often, and I myself have been a part of them on both sides :D
But I think it's hard not to wonder about GOG's curation. I mean, I'm trying right now, here to be as impartial about it as I can, and still I find a few things about it that baffle me. Like the fact that once rejected games are released here often way, way later, after they have been bundled and discounted to death elsewhere. Plenty of diverse, original indie games, that would certainly help with the impression of an annoying trend of pixelated retro "crap". A lot are actually even available DRM-free, just not here. Or finally, the in-development games. It's really hard for me (and maybe here my attempt at impartiality fails me) to justify rejection of finished, complete games, when unfinished ones are sold here. I just cannot wrap my head around a finished, well received game being rejected, when something that's maybe half-complete can be sold here and it's all hunky-dory.
Thing is, curation is not an objective, normative practice; I guess that is why it's not called, say, the GOG filter or the GOG catalogue system or something like that. They probably have some guidelines about what to accept and what to reject, but ultimately it's up to a (I assume) team of people like you or me who not only ostensibly like very different things but also take these decisions based mostly on contingent criteria (this is key) that are inaccessible to us because, on one side, they're personal, and on the other, an issue of GOG's brand. I think that in this case 'curation' doesn't strictly mean QA or a fixed set of objective criteria (finished/not finished), but a selection process that attempts to reflect GOG's brand values (whatever that might be to them) through decisions made at a personal level.
It might be puzzling to us (it is to me, in many ways), but I guess that's not an issue for them, because they're not offering a standardized gatekeeping but something that aligns with what they believe the platform should be or stand for, on one side, and on the other, simply with what their staff likes, at a very precise moment in time. Because of this, the same criteria that made them accept some game might not apply when judging another, which results in situations like having only [i][most/i] of Arcen's games, and not all of them, even though their quality overall is mostly the same.
