The length of the Raiden Shogun story quest can be quite subjective. On average, it might take around 3 to 5 hours. However, if you take your time to enjoy the cutscenes and dialogue fully, it could extend longer.
Well, the canon status of MK comics isn't straightforward. It might be canon within certain story arcs or universes, but not across the board. Different interpretations and continuities can come into play.
One idea could be a Raiden crossover with the Mortal Kombat universe. Raiden could team up with other iconic characters like Scorpion or Sub - Zero to fight a common enemy that threatens both their worlds. Another idea is a crossover with a cyberpunk - themed world. Raiden, with his electric powers, could fit well in a high - tech, dystopian setting, perhaps fighting against corrupt corporations or rogue AIs. And a third idea could be a crossover with a fantasy world, where Raiden's god - like powers make him a key figure in a battle between good and evil magic forces.
The length of the MK9 story varies depending on how quickly you progress and explore all the elements. But on average, it can take several hours to complete the main storyline.
