They need to be more specific with their DRM labels. "Other DRM" isn't good enough. You can often surmise what the DRM is, like the Origin client, but that isn't always the case. Regardless of what one can assume or surmise, they need to provide accurate info that isn't vague.
... so why would one buy something from GamersGate instead of e.g. Steam? I can only think of the price, but then there are also lots of other dirt cheap Steam-key stores, including Humble Bundles.
Frankly, I think GamersGate will continue only as a low-margin Steam key store, if even that.
I've bought 2 games from them that were on sale. Both are DRM-free at GG and are also sold on Steam, Alpha Protocol and STALKER CS. GOG didn't have either of those two when I bought them. GOG have the STALKER series now, and they may eventually sign SEGA. So DRM-free is one reason, but except for cheap casual games and shovelware, I think GOG may eventually have nearly all of what GG have.
You think they're 2nd behind Steam as far as volume of transactions? I wonder if Amazon might handle as many or more than them. Probably not yet.
Doubt either. Amazon seems to have a hand in many things but not great in anything except in books.The way they sell games is a bit allover the shop.Steam.No Steam. Sales have become so so bland - only great deals are the ones where they price match and better a Steam sale....otherwise same old same old. Then you have CAG trying to have their 2cents worth -- check their Amazon thread
