 When the first Mortal Kombat was released on the Super Nintendo  Entertainment System, Nintendo, who had a family acceptability  policy that included the prohibition of graphic depictions of death  and excessive violence in games released on its systems, asked for  the gore from that game to be removed and to tone down the more  gruesome fatalities. Consequently that version sold poorly. As a  result, Nintendo finally agreed to capitulate on those guidelines  for Mortal Kombat II and allowed all the original gore and  fatalities to appear in the US and UK SNES versions (the Japanese  version was censored, such as having green blood), but still put a  warning on the box. The SNES version was considered to be the best  home version available and its sales reflected that.
