Ooh, I should finish God of War II sometime. I've had it since it came out, and haven't played it in ages. It's a pity too, it's such a great game. But now that I have Viewtiful Joe, Beyond Good and Evil, Eternal Darkness, Oblivion, Gears of War, and Dead Rising to play through, I'm at a bit of a loss as to where I should begin.
Anyway, more on topic, Xenogears and Xenosaga. Xenosaga is one of the most epic game series I've ever played (especially Episodes I and III). As for Xenogears, how can you get any more epic than slaying god?
