Took me about 22 hours (-2~3 hours cos I forgot to save and my characters got wiped plus an hour or so of grinding)to clear my first run through the game. Despite some others who found the game lacking, I actually found it rather enjoyable. With that I'll state the pros and cons.

Pros:
+Battle system is similar to Chrono Trigger, which makes it fast pace and exciting
+Really beautiful artwork, and the scenery's amazing.
+Piano BGM, which is unique.
+Lots of customization in terms of skill builds, weapon choices, character/skill names etc.
+Weapon outlook changes as you equip different weapons.
+Character interactions are really cute.
+Cute monsters and bosses. Picture yourself fighting a chibi penguin and an overstuffed baby seal.
+Certain boss fights are rather tough, requiring some character compositions to tide over.
+Cutscenes are done wonderfully.
+Has a decent replay value.

Cons:
-The game is pretty much just snow everywhere.
-Story is too similar to Final Fantasy X and Tales of Symphonia.
-Can't skip cutscenes.
-Even though there's voice acting, it only occurs during combat. And its only in Japanese Dub.
-Many people are facing problems with the XBOX one controller, which tends to screw up the controls. Only way to fix it is to rebind it but there's no way to save it everytime you launch the game.
-Alot of indepth info that are actually missing, which tends to make new players confused and lost. I actually figured out how to use "Momentum" near to the end of the game. Still have 0 idea how to use Flux.
-There's absolutely NO map guidance or navigation. You have to sort of memorize the map/world layout to progress.
-Most boss fights are just tank and spank.
-Positioning is crucial in battles but you have NO control over where your characters stand/move.
-Farming for materials to gain skills/perks may get repititive afterawhile, especially when the mobs don't drop the key item.
-Throughout the game you'll encounter dialogues in which you can make choices, but sadly it has ZERO impact on the game.
-Ending felt abit lacking, with tons of questions left unanswered.

Overall I felt my money was well spent, though some others might disagree. Definitely will recommend people to buy this game when it's on sales.
