I went into this extremely sceptical as I didn't think I'd be interested in a game about "robot dinosaurs. I was pleasantly proved wrong, with what is undoubtedly one of the best games of this console generation.
The Complete Edition also includes the additional 'Frozen Wilds' DLC which adds a solid 10-20 additional hours of gameplay to the base game (20-40 hours depending on your playstyle).
This game is amazingly complex and the visuals are beautiful. There is just so much to do that it can sometimes get overwhelming, but it does keep a player busy - I am yet to finish. There are so many levels of play, that the game literally suits anyone from casual to the die hard gamers. I love Aloy, the female protagonist and I can't get enough of the world and the machines she interacts with. One of my favourite games.
