Then: Where's the Gore?: Mortal Kombat (SNES)

Before Acclaim released Mortal Kombat on consoles, it ran into a major stumbling block: Nintendo. At the time, the company refused to allow blood and gruesome fatalities in the SNES edition. As a result, the red stuff replaced by sweat and lame death sequences. As a result, the Genesis version, complete with "blood code" (ABACABB) became more popular. Nintendo learned its lesson, and a year later allowed Acclaim to make Mortal Kombat II just as bloody as the arcade version.
