Leroux: It will be tough for GOG to directly compete with other shops if they allow their partners to undercut GOG's pricing on Steam, Origin etc. Because the majority of players, even those who would prefer DRM-free builds under equal conditions, will still compare prices before thinking about DRM.
_blueOne: Good shout, however is there a reason to this? As in do GoG take more of a cut than Steam? or is it simply bigger playerbase = cheaper prices from indie devs PoV?
Not usually, sometimes GOG is even cheaper than other stores. It's just some single recent events which made me write that, mainly the new batch of EA games that arrived here like The Saboteur and Crysis which cost 50-100% more on GOG than on the European Steam and Origin stores. Apparantly EA chose to go with the US Steam and Origin prices here, because for some weird reason these games seem to be much more expensive in the US than in European stores, but it's especially weird since GOG has regional pricing for most newer AAA titles, and the result is that while for the US everything seems normal, for Europeans the games are much much more expensive on GOG than in the DRM stores now.
And the second thing I noticed is that the indie game Oxenfree is on sale right now in both the GOG Halloween promo and the Steam Halloween promo, but not for the same discount. So GOG's 60% off is now competing against Steam's 75% off, at the same time. And on top of it, GOG does not offer the soundtrack to Oxenfree, while on Steam, if you buy the game + soundtrack right now, it's still cheaper than the game without soundtrack on GOG costs at the moment.
Anyway, like I said, these are just two specific cases that I'm a bit grumpy about right now, and others here would regard them as petty, I guess, but I still find that kind of worrying, because it seems to indicate that some developers/publishers seem to think that customers here will pay more for DRM-free versions, and maybe they're even right about that. So in a way, if Steam has the monopoly on cheap games, GOG has the monopoly on the DRM-free versions, not in all, but in many cases, and that means publishers can get away with asking higher prices for those here. In these cases, there is no direct competition between the stores and no completely free choice for the customers. If you want the DRM-free version, you'll have to pay whatever they're asking for it here. If, on the other hand, you don't mind DRM that much, the other stores have better offers than GOG. You can't directly compare and say "under the same conditions most people would prefer Steam / GOG".
