I've been harping too much on Drakengard, so to throw it a bone, the story and characters are interesting. I especially love the lore you get from the weapons you unlock, which makes leveling them feel worthwhile.

Also, Ymir's Finger (hammer type weapon) and this short sword I picked up are insanely useful. The hammer weapon just has great knockdown effect which makes dealing with groups so much easier as well as tougher foes. The short sword is awful on its own but it's magic spell, Sword of Damocles is overpowered as hell and leveling it turned out to be super easy.
