There are some games which are visual novels and then there's ones like this which are visual NOVELS!
Seriously though, the writing alone in this game is in a class of its own among the titles available on this site and that's before you mention the great art, music and, last but not least, the battle system.
It strikes such a good balance between actually showing you things and letting you imagine them as you would reading a book.
I can't really blame the creators of games which use English that's barely held together as it's rarely their native language, but it is just such a joy to play something with this much thought and effort put into its storytelling. I could be nitpicky and mention that it feels like there is a bit too much swearing at times and that there are a few "thens" instead of "thans", but I won't even if I just did.
I'm only finished with the first day of the story so far, but am itching to continue on with it.
Cheers!
