I know this comment is far back, so Jim's unlikely to see it, but I wish he'd give some credit to the Youtubers who went through with the Mordor review... and then were clear as day that it was paid off and approved by the company.
I know that Cryoatic, the only Youtuber I watched that did a paid "review" of the game, styled it mostly as a short Let's Play showing off the nemesis system, and then spent a few minutes at the end talking about how the company hired him to make this video and give the game a good review, and he's cool with that because he genuinely thought it was a good game anyway. Cry was explicit about the sponsorship and worked to assure the audience that he wouldn't have done it if he hadn't thought it was good. Maybe that's just a bunch of hot air meant to reassure his viewers, but given Cry's track record, I'm inclined to believe him. He's never really been the sort to care about money or fame, or he's done an incredible job of disguising that fact, since there are multiple instances on both his Twitch and his Tumblr about how he doesn't really like attention and does what he does because he likes playing video games - I mean, the man strives to maintain his anonymity. He's repeatedly tried to lower prices on the merchandise made for his viewers. And he seems to play more obscure indie games than anything else, so it's not like he's reliant on AAA gaming. But most of all, while he didn't go into the detail outlined in this video, he was honest and clear about the sponsorship, and tried to make the review more like a Let's Play so that people could better decide for themselves.
...That kinda turned into a rant about Cry, but the point I'm trying to make is - there are probably other YouTubers out there who did the same, or something similar, or just walked away entirely like TB did. I think they should get some credit, for their honesty if nothing else.
