In retrospective yes you might be right. yet during the story itself it is the deadly allieance itself who is /are the main charachters

ProudNintendofan and Hakasha, you are both right. I mean, I suppose it depends on what perspective you take. From the good point of view, Raiden is the main character, from the evil view - the deadly alliance, I mean, the game's even named after them.

Then there is Reptile, not involved in the intro etc. But if you read his konquest, he is the one who kind of gets Shao Kahn killed - by getting distracted by Nitara, not getting back to inform Kahn of Tsung and Quan's plan, and being there to protect him. Then he gets turned into the freakin Dragon King, so he kinda plays a big role too.

It just seems so any people are important, since MKDA has such a good story.

And when playing MKDA I would have agreed that Kung Lao was the main guy, but I guess that would have been too obvious for MKD. Too bad cus he kicked much ass in DA...

One last thing, you said Lao is dead, I dont think so. Many MKD endings show that the earth fighters were just beaten and captured, not killed..

For once, people other than Liu Kang played equaly important roles in defending earthrealms. Other did battles and failed, others did not, just to keep themselves for the upcoming trials in MKD.
