Sequels can be seen as risky ventures in the gaming industry, but they can also be when a series first finds its voice, like in the case of Mortal Kombat. Mortal Kombat II came out in '93, only a year after its predecessor, and it would immediately set new standards for the franchise and the fighting genre as a whole. It would take two years for Mortal Kombat 3 to follow in '95, which might not seem like long by modern gaming expectations, but speaks to how Mortal Kombat II kept audiences entertained in both arcades and at home. Mortal Kombat is still going strong after more than three decades, and the upcoming Mortal Kombat 1 teases some compelling changes.
