AFAIK CDProjekt was previously called Optimus and it's sub-studio, Optimus Pascal made 6 games on PC. Although they were in polish only, i wouldn't mind seeing em appear at GOG. Since they are a part of CDProjekt RED, the game developer studio created by CDProjekt. Those games in questions are:

- Clash
- Pył (Dust)
- Lasy Podpoduszańskie (Underpillow Forest)
- Sekrety króla (King's Secrets)
- Tuguli: Wieże Aniołów (Tuguli: Angel Towers)
- Zagadki Lwa Leona (Leon The Lion's Riddles)

I think you've answered your own question.
