Hands down one of the best games I've played
Best world - feels just like you're there. so many well hidden areas and things to find and explore
Best balancing - fights are cruelly difficult but always fair. Remains challenging from beginning until the end. Incredibly rewarding.
Best battle mechanics - never played a game before where every single aspect matters and is useful. First time I've actually had to use status effects
Art and music - just incredibly amazing. it's got everything everything from cute, to bizarre, to inappropriate.
Story - very condensed. confusing at first, but makes perfect sense in the end. it takes quite a long time to figure out what's going on as the story and lore are not spoon fed to you. but you will always know what you need to know.
Finding it hard to find absolutely anything to complain about. It's just THAT good.
Probably not the best choice if you're new to JRPGs, but if you are, this is definitely a gem. This will never leave my collection and I'll probably play it again soon. :D
