yogsloth: So tempted to buy more. observer? Sexy brutale? Dang.
You know all I would get is bit trip crapola though.
It's only worth it if you aim for a full GOG collection. If you do and own most of the cheap games, you can get good deals and some "free" small games as bonus. It seams the chances to get big games are lower. I got many cheap games yesterday, before i reached the expensive and newer ones - today was much better and many good deals. So it seams the expensive games are only distributed with high probability if you already own all cheap games.
You may be lucky, but if you want to force your luck you have to buy stars until it says "Gift a star.".
