Seems to me that the "when it's ready" release date should sooth our fears for GW2 at least.
But I guess the difference between a game and a car is that it won't actually kill you if the game has a fault...
Game consumers traditionally don't have the power to demand such high levels of completion. Car buyers do. The CEO of a company who buys a BMW can demand more than ur average gamer.
This is gradually changing however I think. And companies like Anet realise this and are taking gamers seriously.
We are LEGION after all xD
