3D Realms almost had a lawsuit over the Duke Nukem name when they owned that IP. When Captain Planet was on air they changed Nukem to Nukum because of said character on the show
they later changed it back and registered the name after finding out the creator's of that show didn't trademark their character.
The dev's of this game have been pissing off the SJW crowd, They're not wrong tho with some of comments.
