That is also true. By and large I think it is mostly them keeping with two rules: First, keep with the current market trends for MMOs. Makes sense from a financial standpoint. Little risk and greater chance for reward if you play your cards right. Second, don't repeat the mistakes of the past whether they be your own or someone else's. There is much to be learned from history and that holds true for businesses too. I don't deny that this game I love so much can improve. Everything can. But I don't want improvement at the cost of the potential loss of it altogether or loss of friends in game because they can no longer invest what little time they had to begin with.
With risk comes reward but who can say when the risk is greater than the reward? These are things they have to work out on a development basis. Again, Yoshida has been quoted many times as saying there are tons of things he wants to implement but can't. At least he wants to, you know? That has to count for something.
