Sooo, is it easier now for GOG to get their games here, or more unlikely?
Considering the fact that Disney doesn't give a flying fuck about hardcore games i'd say it became more unlikely.
At least when Lucasarts was still independent, some of their older games were released on Steam, so there was a possibility that they would appear here too. Now i really don't think anything will happen, Disney has been closing down their game studios for some time now (RIP Blackrock, Propaganda games) and shifting their focus into mobile and social crap.
They'll probably just sit on these licenses forever. That's how shitty Disney is.
