A fighting game lives or dies by its roster. While a fighting game can have the flashiest animations in the world, and even the most satisfying mechanics, it'll all be for nothing if fans don't gel with the game's roster of fighters - and that's happened on more than one occasion. Thankfully, by most accounts, Mortal Kombat 1 avoids this issue well, with a roster that's packed with both iconic and lesser-known franchise characters, giving fans plenty of variety.
