It worked in the story because immortals were rare, gonna be odd if everybody is one, and if you're not, why play? I'm curious to see what they plan for gameplay. Also wonder if it's hardcore a la diablo hardcore, no head and you need to make a new char
Either way it could be pretty cool and the movie/char creation was pretty impressive.
