If you could change one thing about each FF...

[Wolf Kanno]

...what would you change? Keep down to just one thing that is not it being cancelled or something vague like "I wish it was good".

[Pumpkin]

I. More personality for the main characters
II. Easier
III. More memorable. Have a story that grabs me more
IV. Hard to say, haven't finished it yet!
V. Stronger characters. They were likeable and had potential, but fell a bit short
VI. A bit lighter. Not in mood, because it had humour, but the areas were pretty dark for my liking
VII. Less crude
VIII. Have magic once you hit 100 not be used up so I could actually use magic
IX. More background for certain characters, more screentime
X. Better battle system
XII. Easier
XIII. Less linear

I would make all of them have the battle system of either X-2 or XII.

[Karifean]

I would make them all have XII IZJS's superspeed feature. I've been so spoiled by that L1 button.

[Christmas]

Everyone series get a lightsaber easter egg.

I mean, we know Square is a big fan of Star Wars!
