The GOG Spring Sale ends in just a few days, and until March 29 at 9 a.m. ET, go to gog.com, scroll down to the "Spring Goodies Collection #2" banner, and click the button to get the following:

The soundtrack to Neverwinter Nights by Jeremy Soule is really good: Kingmaker is a massive 175+ page volume of concept art, maps, items, costumes, characters, monsters, and more! The point. That's all I saw, but if you like "Frostpunk," "Children of Malta," "Moonlighter," and "Shadow Tactics," you'll definitely like these goodies too.

One other thing to note, especially if you have a large collection, as they can be a bit hard to find: after claiming your free items, you will find them grouped together in the library under "Spring Sale Goods Collection 2." gog The Spring Sale ends on March 30 at 9:00 a.m. ET.
