I don't know what it's similar to really.

I wouldn't say VII - the opening did scream VII all the way through, but the similarity ends after that.

Design-wise, probably X and it also shares the fun of being the first on the current console generation. It also has the whole thing of a near-mythical world destroyed thousands of years ago.

Story-wise I'd say VIII but our resident VIII obsessive shouldn't get too excited as I'm referring to how weak and nonsensical they both are, lending them well to theories mind you

Characters, I don't know.. seems a bit of an ensemble cast like VI and XII with a lead character in name only, but they're different again and far more interesting than XII's.

If I had to pick one, perhaps X, but certainly not as good.
