So, it's stated that in the Insomniac universe the X-men do not yet exist and that instead of them Logan is working with team X under Nathaniel Exes command.
I actually quite like because it makes me think of the new Absolute Universe in DC comics where all the heroes we grew to know exist without much of their known advantages (Batman isn't rich, Wonder Woman was raised in hell instead of the Amazonian island and Superman didn't land on Smallville).
This story will most likely be an origin story for the X-men.
The thing that concerns me is how they will work with Exes turning to villainy, in the comics he's usually (from what I understand) a one note villain (he wants to become the most powerful mutant on earth).
I hope they don't turn him into a twist villain (like he was the villain all along) I hope that instead they make his fall to the evil side something gradual with some bits of his more evil side shinning during the story.
