It's always boils down to some family rivalry which is just meh. The story is good enough but the gameplay is friggin top notch.
I saw an article recently about how this game already surpassed 2 million copies sold in 2 weeks. Good times. I know they'll think of some crazy way to keep the story going and it'll likely be on the PS5 or whatever their next gen console will be called.
Thankfully I'm all about PC gaming at the moment.
