phaolo: Damn.. GOG come on!
There's also "The Binding of Isaac" for €1.25 (DRM Free)
How is GamersGate compared to GOG?
GG is one my favourite Portals, I bought more games there than on Steam, because you can find rare games there that are hard to find on any other sales portal.
There was some discussion about the notion of 'DRM Free' as GG uses it, as you need to copy the offline installer files out of the installer directory while the GG Download Client is active. A Workaround. IMHO GG never cared to update their Client and so this historical heritage persists.
Because on the newer Mac Side the Installers are DRM FREE as in GOG: you download the Offline installer with the GG Download client and never need to use the client again for that game, as it is meant to be.
That is a bit more of a hassle than necessary but IMHO the GOG download client is also not a good piece of software, slow and inflexible UI and on the Mac side it does not even recognize if the file is already downloaded and redownloads the wohole thing again, I tested that the last time i tried it. An then it has this strange caching behaviour that acts up when the App is under heavy load and crashes. The App is not design for heavy usage. I don't use the GOG Downloader at all anymore.
Another upside of GG is Blue Coins 5% payback for each purchase and you get Coins for reviewing, rating and affiliating. So if you are persitant you get some games without paying money. BUt don't get you hopes up too high. ;)
And you can give your games back without any question asked within 14 days as long as you did not download/activate it. When GOG's new return policy is in place it surpasses every other site out there.
Support on GG never left me hanging, for the very few occasions I hat to use it. They were always helpful but takes some time for them to respond.
Unfortunately, besides the Game Tutor section there is no commnity interaction possible.
While the GOG community is pretty great.
my 2 cents :)
