bler144: Yeah, I already owned it on Steam, and got one of the free GOG keys in that giveaway just in case I ever want to play through it again after Steam ceases to exist.
Prohzac: Whaaa? Steam better not die, until I move my Thief and LoK collection from there to here! And in this case, you better get latest Thief remake, Gog. Ha! I bet it's somewhere on wish-list there. Gotta vote yes!
Well good chance is, that if steam goes under, things aren't rosy for gog either. Lots of companies trying to get into the market with their own distribution channels (however silly that is) and others trying to control it. Microsoft tried (because hey it works for consoles, it surely must work the same way on pc), failed , and are now trying again (and hopefully fail again...).
But at some point it might just work. Heck even steam is trying to do that now.
