I haven't bought Oblivion yet, It's on my to buy list .But i have played Heavenly Sword...The graphics and game play were really good.. but i kinda felt like I was playing God of War..The main weapon has a lot of the same characteristics as the weapons in God of War,,Just rolled into one..Combo moves work the same way..And it was a little sort..But all and all Its a must have for the collection.
