FF IV
+ Pretty solid game overall...
- ...nothing more than that, though

FF V
+ Awesome gameplay!
- ...but lacks the long, fun, strategic superboss battles to back it up.

FF VI
+ The story is quite an experience
- The gameplay leaves a lot to be desired

FF VII
+ Moddable like crazy
- Imbalanced like crazy

Dirge of Cerberus
+ Pretty fun challenges
- Can get repetitive and boring at times

FF VIII
+ Best minigame in the series
- Bad combination of enemies leveling with you and you getting stronger without leveling

FF IX
+ All characters feel unique and distinct from one another in gameplay
- Tetra Master isn't nearly as fun as Triple Triad was

FF X
+ The story
- Being able to stat-max this easily and readily

FF X-2
+ The gameplay
- You absolutely shouldn't be able to get "100% Completion" in just one playthrough

FF XII
+ IZJS
- Original License Board

FF XIII
+ OH MY GOD I CAN PICK MY COMMANDS *BEFORE* THE ATB GAUGE FILLS UP, I'M SO DAMN HAPPY WHY CAN'T ANY OF THE OTHER GAMES HAVE THIS FEATURE
- Sidequests and trophies are pretty grindy

FF XIII-2
+ Paradox Endings
- Fighting against the computer's tendency to have the squishy damage dealer walk towards and stand right next to the tank so they get hit by AoE attacks
