We've had MK:M, MK:SF and the most promising of the three MK:SM but what if we had a game focused on an entirely new story of characters and events prequal/sequal to the tournmaent events? It wouldn't be something like Shujinko's Konquest though.

Example:

#1 You lead an OIA (Outerworld Investigation Agency) squad through the decayed realm of Outworld and Earth hunting down criminals such as Reptile for starters. You move through familiar landcsapes like the Wastelands, Living Forest etc. You can fight melee style or in third person view using guns.

#2 Chosen by the Elder Gods you travel the realms meeting new and familiar warriors to compete against to prepare you for the Mortal Kombat tournament. You would move through Earth, Zaterra, Edenia, Chaosrealm, Orderrealm and eventually Outworld. As in Legacy of Kain for each boss you beat you gain their abilities. Such abilities could be invisibility by killing the Saurians in Zaterra.

#3 This would be considered your Unreal Tournament kind of game. You choose between various clans/races such as the White Lotus, Lin Kuei, Special Forces, Tartakans, Black Dragon and Red Dragon to start and you duke it out in teams over the various realms. Later you can unlock teams like the Raptors, Brothers of the Shadow, Tekunin etc.
