You're not wrong.

I mean, on the most surface level, it's exactly that genre. But that would be like saying Game of Thrones is just a show about dragons and swords. Shows and video games surrounding those genres are definitely not new.

What made the game, and hopefully this series, different is the approach, not the setting.

It's a story about relationships and choices, ones where moral black and white doesn't exist. Where your perspective can make you the good or bad guy. Where the choices a person makes doesn't easily define them as such, where you are forced to see things from different perspectives. (esp TLoU2)

Most TV forcefeeds you this on a spoon. These are the bad guys! They do bad things! These are the good guys! Everything they do is right! While TLoU makes it obvious that things are not so cut and dry. I really hope the show captures that aspect of the games.
