I'm so backlogged that I almost swore to myself that I wouldn't get anything in this sale, but then Kult: Heretic Kingdoms (I like that title better) came up for 1,39 euros, the equivalent of a not very expensive ice cream. I've been planning to play that game for quite a while (it has Tom Baker, aka Dr Who, narrating it!) and I'm in the mood for that kind of game right now, so I'll probably not throw it on the pile and let it collect dust.
Then another game that I wanted even more, Shadow Man, turned up and I pounced on it, because it was going away quickly. Wow, a critical hit! Shadow Man is the game on my wishlist that I wanted the most and I got it for free. Lol, that makes it 9 free games out of 25 in my GoG library or 36 %, a much larger number than the amount of games I've played in either my Steam or GoG library.
