I have no idea how they are gonna use the nemesis system in a WW game. Glad Gail Simone is part of it
In Shadow of Mordor you leave physical scars on your enemies, and their appearance and personality changes based on the way you hurt them previously, or how they killed you.
In a Wonder Woman game she won't be killed constantly, the game will just reset to before she died, and she won't leave physical scars on the enemies.
So the Nemesis system will work differently.
