A sad reminder that, unfortunaly, Duke is a product of his time period and it would be hard to make him work in today's world.
He's just like the movies who he parodies, a time capsule to the 80's and 90's, hell, his games were still making Monica Lewinski jokes as of late as 2002 and you saw how the final version of Duke Forever tried to emulate all the subgenres and changes the fps genre had seen since '96.

The biggest difference is that Duke was a successful parody, at least at first. Forspoken appears to be played straight.
