I want a hack and slash game with cool acrobatics and similar requirements as warrior within.
God Of War series? Not sure about acrobatics (although your character does jump and flip about during attacks) but certainly has lots of hack and slash.
You may want to try Dante's Inferno. As the name suggests, it's based on Dante Alighieri's Divina Commedia.
It's very hack n' slash-y, it's dark like PoP: WW, the story is just as epic as it was 700 years ago.
Maybe Bayonetta? I heard it's a pretty decent Action/Hack n Slash like game if that's what you are looking for. Can't really comment to much on the game/genre in general though as it's not one of my strong areas.
