I have too much to say about this game.
It's by no means perfect, there's a fair bit of unnecesary grinding, but once you power through it you're treated to one of the most interesting, spiteful and thoughtful stories of all time with amazing music, voice acting and a reason to give the other games a go or maybe even a new rabbit hole to look into.
Don't play Drakengard though, just watch the important bits on Youtube.
