They dont need to state we already know their reviews are insufficient to rush the videos/articles out.
Wich difficulty? Normal.
Completion rate? Just the regular game. No extras (possibly tried them and left them behind).
I have seen people say Lords of shadow 2 is a cakewalk... they obviously didnt complete those Kleidos challenges. That is why i dont trust reviews. They always omit important information.
Actually only one person on this website i saw post a review and was one of the few that noticed the real faults with the game: The auto-targeting and camera are seriously off. You wont notice that unless you are playing a challenge though. Otherwise you only notice it during some silly puzzles during the main quest.
The stealth section that everyone loves to hate and is understandable accounts for about 2% of the whole game. Its meaningless compared to the real issues of the game if you play it on a harder difficulty mode. The combat beeing frustrating because of technical issues at times i account as a more important flaw that none of the commercial reviewers could see. Hmmmmmmm... i wonder why...
