How Do You Group Final Fantasy Titles?

[Carl the Llama]

IN The Beginning: Final Fantasy 1
The Japanese Era: Final Fantasy 2, Final Fantasy 3
The Golden Age (AKA God Tier): Final Fantasy 4 through 6
The Dark Times (AKA crap Tier made of poo and fail): Final Farting-sea 7, 8, 10, 12, 13, 13-2
The Renaissance: Final Fantasy 9, Crystal Chronicles
The changing-clothes Era: Final Fantasy 10-2

A part of me wants to punch you, but the other part wants to hug you.

I am conflicted.

Its called Ambivalence, as for my feelings towards Botchmun, I am only feeling the former...

Anyways I would group them as follows:

God Tier: Final Fantasy VII, IX.
Old School: I-VI (good enough but doesn't come close to God Tier).
Fun Tier: XIII-2, X-2, Crisis Core and X.
Military: XII, VIII.
Time sink: XIV, XI.
Indifferent: XIII.
