Need more Witcherstuff in your life? Sure you do! It's time to get cozy.
CD Projekt RED is giving out a massive collection of art, soundtracks, wallpapers, and making-of videos for the whole video game series. You can download the Witcher Goodies Collection until 7:00 a.m. Pacific on March 18, 2020. Once claimed (from the GOG.com front page), you'll be able to download digital "goodie" packs for The Witcher, The Witcher 2, The Witcher 3, and Thronebreaker.
There's also an up-to-4K download for the two-hour Witcher 3concert that was performed in Kraków, Poland. Basically, if you're a fan, there's a lot to pore over. These digital packs are in the 3–4GB range.
As Ice-T would put it, this is "Gamer Stuff" through and through.
I downloaded the Witcher 3goodie pack out of curiosity. It includes a pdf of the art book, additional art pieces, avatars, comics, character renders, wallpapers, a world map, paper toys, trailers, music, and a compendium. If nothing else, you'll want to nab the soundtracks for The Witcher 3: Wild Hunt, Hearts of Stone, and Blood and Wine – they're available in mp3 and flac form. Again, that's just one pack.
CD Projekt RED's games are also heavily discounted thanks to GOG's 2020 Spring Sale. If you're looking to stock up on those or other PC titles right now, note that this sale runs until March 30, 2020.
