ZivilSword: You are free not to buy on GOG. They do not lie but say they will not offer Linux versions. If you prefer a Linux system to play, you certainly won’t do any good buying games here. But since you bought here, I presume you wanted to play those games on Windows (or maybe Mac)?
I know it’s kind of silly not to offer the Linux versions for free or unsupported but there was already a big discussion about this. You simply cannot offer unsupported things. The problems arising with pissed of customers would be higher than those by simply saying “no Linux”.
For games like FTL it’s quite senseless, but I have to say, you did not necessarily need to buy it on Steam because the developer offers the game on his homepage via Humble Store, and it’s the same price (even with discounts)
and the developer would have got more revenue
and you have got it DRM-free …
The Humble Bundles (or other bundles) are great for getting Linux versions. I also think you are morally allowed to just pirate a Linux version if you already bought a Win version on GOG – but that’s a personal decision one need to make.
Of course I won't be buying anything more here for now.
I only want to encourage other linux enthusiast to consider redirecting their money flow to services which doesn't actively lock out linux versions of games. Steam happens to be such a service.
I started to collect games here with a believe that when linux version of particular game is released gog will most likely include it in download section. I was surprised when they just refused to do so.
For instance I bought Legend Of Grimmrock which at time of purchase was available only to windows users. Now its available to linux as well and it hurts my feelings that I cannot download it from here.
I had a dream that gog.com will be my ultimate library of all beloved games.
I was buying games of all kind. Some of them I bought just in tribute to their greatness and to redeem myself of playing them unlicensed years ago when I was a kid.
This dream is no longer, due to gog.com somehow actively excluding linux binaries from download section.
I hope you understand that there was a really personal reason I came here. I wish I could continue to use the service but I can't. Continuing using this service kills the very incentive of ultimate game library of choice.
And to be clear. GoG is awesome for somebody who cares only about playing on windows. They do a great job providing windows users with good old games.
