And to the people dreading "starting over", you do that in every Final Fantasy game, and this is no different. It's a different game, it will have different memorable characters, and a whole different battle system.
I'm a completionist and I generally like to play my games to the (comfortable) extent to which they can be played, which I haven't quite done with this one.
Can you honestly say you are having more fun today than when you started however many years ago and everything was new to you?
Yes. I've since learned a fairly great deal about most of the game and how it works, and friends/acquaintances generally look to me as a source of info on various things when they are unable to or can't be arsed to go find it on the wiki or whatever. I began as a WHM mainly to be able to help folks out, and I've since maxed that out along with a number of other support jobs. I've more or less become what I wanted to be when I started playing, which is a good feeling. I can actually DO some of the stuff I remember seeing the "big boys" doing when I started, yet I understand that there's still room for improvement, and it keeps me going.
There is something to be said for the allure and wonder of a game that's brand new to you, and I was certainly keeping much higher playtime/day figures (not to mention much unhealthier RL habits) during my first few months of playing this game. But I've been a gamer for pretty much as long as I can remember, and I've always found that that "ooh new and shiny!" feeling always passes eventually with every single game I've played, no matter how awesome it is. It's very similar to what parents experience with their spoiled children; no matter how badly they tell you that they want you to buy X silly new toy for them, you just know that if you do, after a few months or so that toy will be discarded to the corner and begin collecting dust. What should be looked at is how well the game keeps you hooked even after that "new and shiny!" feeling goes away.
