Battle System - about equal
FF13 pros - You could advance stats much further from crystarium and weapon customization, there was a lot tougher boss battles that took some serious strategic planning unlike the sequel where normal mode is still easy mode practically(I'm not counting dlc). You had summons. shrouds was cool.
FF13 - cons - gil was ridiculously hard to come by making weapon upgrades take forever and once your party leader died it was over. You couldn't switch party leaders during battle. Fights were slower. Crystarium cap limitations throughout the game was retarded.
FF13-2 - pros - quick battles and super quick battles after you obtain all fragments. Having the advantage to switch leaders during battle. actually being able to obtain gil from battles like you should have been able to on FF13.
FF13-2 - cons - mog clock feature and monsters materializing only when your near, not much challenge, not able to expand stats as much as FF13. I liked weapon upgrades opposed to monster upgrade even tho the gill and components was hours of grinding on FF13 . no summons and no shrouds.

they both should have an auto-battle customize feature to where you can organize their priorities of auto-battle sorta like FF12 so your medic don't use esuna instead of cure when your almost dead or synergist cast buffs in a certain order


Sidequest - for obvious reasons FF13-2 takes the lead. I kept hoping you would go to the past before AF timeline and not just further in the future, but at least there was more to do than just mind numbing missions and endless grindfest like FF13.

Storyline - for obvious reasons FF13 takes the lead. I never thought I'd say I appreciate and respect FF13's storyline until I played FF13-2 all the way through and I noticed how empty the storyline is on FF13-2. Neither of them are great, but at least FF13 was consistent. Only real advantage FF13-2 had over FF13 is Serah made a much less annoying narrator than Vanille. Yeah I know, I judge these games harshly.

Soundtrack - About even only because some of the best tracks from FF13 are carried over to FF13-2. Music was the best quality of both these games.

Ending - FF13... no spoilers but I think most would agree ff13-2 ending made you go "WTF?" FF13 ending wasn't great but it was at least complete.

Overall - Tied only because FF13-2's sidequest makes up for the rest. They both really sucked in opposite areas but they sucked equally. They are both games worth playing all way through once and then move on to the next game. They both are a disgrace to the Final Fantasy series imo. I am still bitter over time and money wasted on incomplete games and want Squaresoft back to how they use to be before the merge of Square Enix.
