I think everyone is fear mongering on these companies, we don't know the exact terms and if they really are for 'reviews'. Like that British critic said, he doesn't do reviews but is forced to asked for review copies to do his 'WTF Is...' segments, where he basically tells you what the game is. Personally, most of these guys that do YouTube are entertainers, so them doing 'let's play' of Shadow of Mordor for money is going to be what it sounds like, them making stupid jokes while playing the game. Should they get a brand deal and make money on top? Sure why not, as long as they aren't forced to make up lies about the game while doing let's play and honestly they don't have to. I think the game lends itself well for 'Let's Play' fanbase.
Now if they paid for a review score, then that is shit. I can see why people are freaking out at this aspect and honestly, any review that doesn't mention obvious criticism, like how repetitive the single player is, is really doing themsevles a disfavor in the long run.
I'm looking at the game's promotional image and IGN, Polygon and Joystiq all have their reviews on the cover the game. Do you think that is a brand deal as well?
Funny we just talked to the Joystiq managing editor the other day about PSO, I would have been tempted to ask her about that off the air if I knew about the story.
Either way, I'm not 100% against it, it just depends on the context and what they are paying for. Entertainment videos like Conan's Clueless Gamer doesn't bother me, fake review scores do.
