I beat the game sunday (14 hours) and I give a solid 8 depiste the flaws.
this game was a suprise to me and I'm happy with it, I like stealth like MGS and I have so much fun with this game .
Now I understand how the game works and my second run is way better
We are definitely on the same page

The game certainly is a surprise to me as well and I think that a lot of reviewers were quite harsh on it.
Sure it does have problems, it certainly isnt a masterpiece, but it is not a 5 or 6 game as well.
