What's the greatest video role-playing game of all time?

I could make convincing arguments for "Xenogears," "Chrono Trigger" or "Phantasy Star." Each has the epic sweep, the time- and space-spanning sense of wonder that many of us crave from the genre. "Xenogears," for example, involves no less than the death of God. Of course, "Final Fantasy" and even "Pokemon" have their partisans, and old-timers recall the blocky eight-bit graphics of computer RPGs like "Ultima" and "Wizardry" with awe.
