Why do you say that it's 50-60 hours if you do all sidequests? I read that it's 40 or 80 hours depending on how many sidequests you do. The box says it has 100 hours of gameplay. What is everybody's thoughts on this topic?

Gah! Let me beat Final Fantasy XII and Rogue Galaxy and Alundra 1! I'm awaiting a new Zephyr Xbox 360 with Mass Effect and Blue Dragon!!!
