Do you guys remember Call of Duty Ghosts aka the worst Call of Duty in the series?
Well IGN have it a 88. Link: http://www.ign.com/articles/2013/11/05/call-of-duty-ghosts-review
Meaning that somehow, in the IGN twisted universe the worst Call of Duty is equal to the best Uncharted.
Here is a link of the current 88 IGN review for Uncharted 4: https://www.youtube.com/watch?v=zIjQCu8y2EE
If you don't want to give IGN more clicks, let me break it down to you:
The person in charge of reviewing Uncharted 4: Lucy O'Brien, has no idea of how to review a game from a technical and professional point of view. She simply had an idea of the game in her mind (probably a more simple idea) , and since the game did not follow the idea in her head, she decided to deduct 12 points from the score.
