FYI I've just merged all the "Latest [Platform X] Giveaway" threads into one. So this thread is now the place to announce any Steam/GOG/Humble Bundle/Epic/etc. game giveaways. And I would suggest that also includes any future games that show up on GOG Connect, even though I didn't merge that thread
into this one, since it has some discussion that I felt should remain separate from this thread.
