I believe the correct outrage should be at Ubi releasing FC5 DLC and calling it a new game.
The price they have it as very much shows they get its simply Stand alone expansion. Like Uncharted did and Dying light.
Nothing wrong with that either as its not the same game. Might be the same map, but thats like saying you are mad that Witcher 3 has DLC that uses the same world map or something.....
Budget priced and doesn't seem to be trying to fool anyone into believing its at the full scale of a Far Cry that is numbered so I think its far.
