Don't do a review, how about we all give a reason why it's awesome and you read them out in a video? Kind of like a collaboration review.

I'd do something a little more creative, like a short "the good, the bad and the ugly" or something on the game. Reviewing a game like this would take ages to get into everything the game has to offer, and there's already a lot of guides / advice out there by people who have put literally thousands of hours into the Souls games and understand the games inside and out.
