Lair of the Clockwork God released today on Steam, but for some reason not here even though the other Size Five Games titles are here. That's a bummer! I can't find any mention of it's coming here eventually either. Let's hope it won't take too long, I can't imagine it was rejected.
"Conglomerate 451" is also coming to GOG only next week. Despite having already been released on steam yesterday.
For whatever reason some publishers only want to release on GOG after the initial steam sales are done.
