Found out something very troubling near the end of X2. Go down one of the holes at the temples on chapter five and reach the Farplane (You'll know you're there cause you'll meet LeBlanc, Ormi and Logos.) Go back to the ship via the save point and talk to Shinra. He'll start going on about how the Farplane has infinite energy and how he could make machines that tap into it. Hmm is this the start of the Shinra Corporation? Might X and X2 be prequels to VII? Could Yunas quest inadvertidly lead to the creation of Sephiroth? Am I reading to much into this? You decide.
