Rubbish.
Time has shown again and again that people, not only in games but in other forms of developement, benefit from an outside point of view.
Many Developers run a serious risk of losing touch if they assume they know it all without any critical advice.
Well, they don't need a forum or something to give the feedback they need.
In the end sales is usually the most important feedback, high sales? They like it.
Not saying that it's the best feedback, but compared to forum feedback...
Forums are not best known for the best of ideas, the amount of stupid, bad or just plain [censored] ideas drains out the good ones.
Not to mention all the good ones that get ignored.
At least sales just state the facts without and buts and ifs.
Of course, in a franchise sales are less definitive as feedback due to people buying it because of being a sequel, but then the next game usually tanks in sales.
Game of the Year... When did Spike TV become the sole authority on the greatest game of the year? I know there are several other websites and magazines that also gave it the award but Spike TV is the main one everyone is talking about when they say "Game of the Year." To be honest, the Spike VGAs is a joke and how they ever got involved as a respected game awards show is beyond me. I bet most of the people that voted didn't even make it through the entire game before doing so.
Almost everyone Game of the Year award is pretty much worthless in this day and age, between the bad categories and the votes by public there is not a lot of room for proper evaluation of what is a good game.
If you ask me you should disregard any Game of the Year or other awards you see on a box and check it out yourself, they carry as much value as some random guys approval.
