They should obviously expand the world and available areas to explore, in a much broader way than the first game (which it sounds like they are doing anyway).

They need to completly scrap or update the crystarium leveling system, or at least take away the forced caps on levelling, that was my biggest bugbear, that each chapter you could only level up so far and NO further. It seemed like the game developers were forcing you to the play the game only as they wanted, which for an rpg is appaling.

And also scrap or completly overhaul the weapons/armour levelling thing.

And change the freaking stingy gil thing, this game was like the worlds strictest and meanest bank who would only give you money if you WORKED for it by slaying uber turtles!! And the only way to kill them was to level up a LOT, including your equipment, which is what you wanted the money for in the first place arrgghhh the irrational logic hurts!!!!!

And enough with the forced and completly unbalanced party setups, vanille and sazh, compared with lightning and hope, hello!! The former way underpowered and annoying, the latter too easy.

I could go on but i need to breathe....
