HiPhish: If I gathered a bunch of Fastspring links and collected them on a site, would that turn Fastspring into something like the Mac App Store? No it wouldn't, it's still just an unofficial collection of links.
Humble Store is much more than just a collection of links. They have
support, they organize promotions/sales (Humble (Indie) Bundles), they host the files, they take a cut from the sales etc. So it is much more than a mere links page, like some torrent site.
HiPhish: Besides, I'm not saying you can't compare Humble Store and GoG, I'm just pointing out that they are not the same thing. Apples and bananas are not he same thing, but you can still compare them to a certain extent.
I got the vibe that it is ok to compare them, as long as you don't mention any cons of the Humble Store. Because to all of them the reply would be "You can't damn Humble Store for having incoherent installers and not offering patches, because they don't even try to control it but leave it up to the game developers/publishers.". Yet, to me as a customer, it certainly affects how I feel when making purchases from the site. So of course I can mention those as cons of HS/HB, when compared to buying same games from GOG.
HiPhish: Personally I'm fine with the Humble Store, I don't really care about extras like wallpapers or avatars and I don't need community forums. Just give me my games DRM-free, that's all I'm asking for. I bought FTL and Dungeons of Dredmore via Humble Store.
I'm fine with HS/HB too (I have several dozen games from them) and I am after only the DRM-free installers really (just like in GOG), but I still recognize that getting the DRM-free installers from GOG is generally a better experience for me, for the reasons I mentioned before. It doesn't really matter to me why it is a better experience, e.g. "HS doesn't try to control it the same way like GOG.". Well then, it is clearly a downside on HB/HS that they don't control it.
