There's a ton of stuff to do

You can rush through and clear the story sort of fast, I've heard around 40 hours or so. But the world is absolutely huge and there's a ton of other quests to do, things to collect, places to explore, and things to kill. I'm already 25 hours into it and I only completed 4 out of 12 missions with doing some of the side quests. I only explored the first continent, a third of another one, and a quarter of another one, and there's five total.
