Yeah it's just like it is with music. Old people like David Gilmour from Pink Floyd, Black Sabbath can't create any decent music. Miley Cyrus, Bieber - the young, the hungry, the passionate are successful because they make the quality products.
As a former developer in the game industry I can assure you that there is no correlation between creative talent and age. You have it or you don't, and if you have it, it generally just gets better with time.
Sometimes I think Blizzard are too full of themselves, for example one of their lead people who was quoted recently saying something of the sorts "well if you don't like the new models you can always pay 15$ for a change", as if because it's THEM making new models then everyone will be absolutely happy with how their characters' faces transition will go from low polygon to high polygon, and merely suggesting that not everyone will be happy is blasphemy.
I see a lot of arrogant replies in the blue posts too, like someone makes a valid point and they get some dismissive one liner as reply, while other pointless questions especially about things like battle pets and such get these long winded replies which don't say much at all or which try to make it sound like it's such a difficult task for them, I dunno, I don't think that age affects creativity, but it sure does affect one's level of being full of oneself, take it as you want.
I think the people who start wow now are too young. And spend too much time with tablets and other wierd stuff!
"And all those exclamation marks, you notice? Five?
A sure sign of someone who wears his underpants on his head."
Damn, I guess George R.R. Martin should retire then, he is clearly too old and needs to just retire and enjoy his riches.
I don't think it's their ages. Activision should clean out some of the current team and hire new developers and writers. Someone who gives a shit about what the players think.
Funny, i thought WoW started heading in the direction it has when most of the OLD guys switched to working on Titan...lol
