Beautiful game (thus far at least) -- though I liked Odin Sphere's story more. The characters in this one aren't as likable (again, based on what I've played thus far).
Not sure about the HD ports, but if you want to play these, I'd recommend picking it up soon. Newegg had this for $12.99 + FS and it's now OOS and doubtful Newegg is getting a new shipment.
IOW, once these copies are gone, your next stop will be ebay/half.com for used copies.
