First of all, welcome and thanks for posting. However, I am curious. Even if someone isn't bribed outright, don't you think there's some pressure to not bag on big sponsors too often? I mean, we all watched what happened to Gerstmann, after all.
Also, I often see what I call "movie critic syndrome". This is basically the same thing you see in movie critics, they take so much stuff in they begin to lose the ability to see what a casual viewer sees, and the audience they can speak to gets reduced. It's like asking a cameraman for porno films to review porn. The constant exposure is going to screw up the communication most of the time.
Now, there are clearly decent reviewers, but honestly how do I find one. Go ahead and look at the DA2 page on Metacritic. Where in all that mess do I even begin? I remember when The Firingsquad microwaved Daikatana and told Romero to stuff it, I don't see that these days (except for Yahtzee, but that's his whole routine to be negative about everything).
I mean, how much DA2 did a reviewer have to play before he said "YOu know what, I'm sick of this laziness and this cave, fuck you Bioware, this game is shit and you could have done better!"? I haven't read that review, and if it was published it was well outside the initial sales window of the game. Where was the courage to actually damage Bioware's sales on this one? It happened anyway and they deserved it, but no reviewers were calling for their heads.
