Sin6ularity: You don't seem to be that bothered by DRM, and so no point to buying the same games here again, especially as you might end up with a lesser version in some cases.
I am guessing you came here for the few games you cannot buy elsewhere, as prices at DRM stores, especially Steam are roughly on par with GOG, especially sale prices, so no reason to buy here instead of there, unless it is DRM-Free you are keen on, or taking advantage of a sale while you can, remembering of course, that you may end up with a lesser or abandoned version here.
I am bothered by DRM, but too late I already bought bunch of DRM games elsewhere, all I can do is trying to focus on gog games.
Actually I came here cause I don`t like steam much, community is very toxic, lot of angry kids, as an old man I got tired of that. Other thing is games became so cheap, so easy to get, almost everywhere you go they bombard you with cheap keys, so games lost value, at least they did for me. So I decided I need a change, I like single player games, I almost never play any online game and I like to play them in peace. Those were the reason I came.
About DRM I know very little about it only from what I heard that you own the game you buy and can play without client and that`s about it....
I still think I made right decision coming here.
