I agree, I am not surprised that they do things like that one bit, I would prefer they not do things like that, but the reality is there are a lot of dishonest people out there, a large concentration of them seem to be at EA, or come out when studios fall under their wing.
I hate to say it but this probably wasn't a case of dishonesty or some internally promoted nefarious actions. Consider how it must feel to be an employee at Bioware right about now. You just spent a year and half of your life working on a game, and when it comes out, it is blasted by fans and reviewers. I think that any of us finding ourselves in that position would be tempted to jump on metacritics and post a more favorable review. In all honesty, most of the reviews on metacritics are overly harsh and give the game no credit for actually being at least partially fun.
