On the one hand I like GOG because it has no DRM and has better prices (in my country) than Steam and I have the feeling that on the one hand it follows more the open source philosophy than Steam itself, but Steam has helped enormously to play Windows games on Linux, so I haven’t really made up my mind.
On the one hand I want to buy on Steam for the convenience, but on the other hand I prefer GOG because (in my country) is cheaper. Which platform do you prefer and why?
To give an example, The Binding of Isaac: Rebirth is currently $15 on Steam with regional pricing, but on GOG it’s worth just $6.
When its cheap, I sometimes buy on GOG, but its almost always more expensive than Steam in my region, even before accounting for bundles, which is how I buy the majority of my games. It also doesn’t help that most of the games I play aren’t on even GOG, when I do go to look, discoverability isn’t great, and I’ve had some issues with GOG’s support in the past (nothing major, just a pain compared to Steam).
I do like the Idea of GOG, but with developers/publishers generally being uncooperative with publishing off-Steam, and GOG just missing too many features anyway, I can rarely justify it.
