Screenshots of an alpha version of the Witcher 1.
(click on images to browse through, I couldn't embed them here).
Site is in Polish, so I will loosely translate the short stories they share with the images:
Back then, the studio was located in Łódź, not Warsaw. The game was being developed using the engine from a game called
Mortyr (FPS). It wasn't the first and only Witcher game being in the works - Metropolis Software(started by Adrian Chmielarz, who later created People Can Fly) grabbed the rights to the game first. Their action adventure Witcher game never hit the market and the license was used to develop a simple mobile game. Metropolis had rights to create only one game, so it was time for CD Projekt to pay a visit to Mr. Andrzej Sapkowski...
Back then, the concept of the Witcher was close to those of Dungeon Siege or Baldur's Gate: Dark Alliance. The publisher was aware that games similar to Diablo are selling well and wanted to follow this trend. CD Projekt actually started making games thanks to Baldur's Gate. The Dark Alliance sequel was planned for consoles only and that wasn't promising too high sales in a country dominated by PCs. Interplay didn't plan to make a PC version but didn't mind CD Projekt doing it. So the Polish studio took the challenge.
Eventually, Interplay's financial trouble led to CD Projekt having an open project and not knowing what to do with it. The idea was to change it into something of their own. And if it was supposed to be fantasy, it could only be Sapkowski. That's how the virtual Witcher started his second life.
Interestingly, Geralt wasn't supposed to be the main character. The player would play as an anonymous Witcher that gains skills and experience throughout the game. Geralt already being a killing machine didn't really suit that concept. After CD Projekt RED chose the White Wolf after some time, there was only one way to translate it into gameplay ideas - amnesia.
After a year, a demo was complete and shown by Marcin Iwiński and Michał Kiciński to world's biggest publishers. Adam Badowski tried to discourage them because the demo, according to him, "sucked". That's also when CDPR moved the development from Łódź to Warsaw.
The screens are from alpha version of the Witcher, dated May 2003. You could choose your character's gender(yep, you could play a female Witcher!). The creators also planned to include online mode option.
