Just got to Chapter 5. Didn't check the clock, but I was over fifteen hours last time I checked (might be near 20 hrs). Played for about 5-6 hours straight today (just breaking for lunch), which I normally don't do.
Game is definitely good despite the overarching narrative being rough. I do know what my next mission is and a bit beyond that and do have an idea about what it's building up to, so it's better than some other Final Fantasy games.
Lots of sub-quests to do (of varying excitement), and I think I've only explored about half the map. Chocobos are fun, as is fishing. Like the pictures/cooking/camping at the end of the day. I miss treasure chests. You pretty much have to do your sub-quests to get a decent amount of gold unless you're selling stuff.
It also seems like weapons/etc and spells aren't as important as other games in the series. Spells are something to throw in once in a while. I am liking the battle system a little more with wait mode, but the camera makes it hard to dodge stuff when you're facing more than a couple enemies at once. I'm hoping it gets better as I get some new stuff unlocked. Chapter 3 dungeon did throw enough at me to drain a good portion of my initial supplies.
They should have added them to your phone somehow. In fact, all quests should have able to be completed via the phone.
Yep, also you should be able to accept more than one hunt at once as well (and set whichever active one you want to do in the menu).
