With the Genesis often outselling the SNES at a ratio of 2:1 , Nintendo and Sega both focused heavily on impression management of the market , even going to the point of deception , with Nintendo claiming they had sold more consoles in 1991 than they actually had , and forecasting they would sell 6 million consoles by the end of 1992 , while their actual U.S. install base at the end of 1992 was only just more than 4 million units .
