Saber Interactive, the company behind Warhammer 40,000: Space Marine 2, has denied it replaced a writer with ChatGPT, but admitted its new taxi game Rideshare Stimulator uses AI "by necessity." But in highlighting Rideshare Stimulator and its cheeky jibes, Saber Interactive also invited criticism from a former writer on the project, Stella Sacco, who claimed she was "replaced" by ChatGPT by Saber while working on the Rideshare Stimulator project at development studio Unigine. And Saber replaced me with ChatGPT midway through development. "Neither Saber nor Unigine have replaced any writers with AI for Rideshare or any other game," Saber said in a statement to PC Gamer. The Steam forum for Rideshare Stimulator is packed with complaints, with many calling for an AI disclosure on Valve's platform.
