I'm an engineer, my knowledge don't come for free :P And I wish it were like that and not the Laplace transforms, advanced integration and differentiation, etc. I have to do. Well it doesn't fit too thematically as geralt is a very lone wolf character and doesn't play too well with others. Perhaps if another game is released in the series set in another time about the witchers and not just geralt. People have complained about not having an option to play as a female in the story. There are decisions they have made to be true to the source material and theme, and to not compromise on just to increase it's gameplay features.
