I personally think your a fool if you just rent it just my personal opinion
First off people need to cut out with garbage God Of War comparing in some ways it does play as God Of War but Nariko has WAY more variation then Kratos does Also where Heavenly Sword shines way more then God Of War is actual character depth and just great freaking awesome story each character was put together excellent and you actually feel sorry for some of them as the story goes on an you kinda grow attached to them in some ways for me it was Nariko/Roach/Kai
The Sixiaxis was great in this game it took a few trys but its awesome specially using Kai an shooting the arrows at other soldiers it just feels so rewarding specially when you shoot them from such a long distance As for graphics i mean theres really nothing i need to say but amazing really the facial expressions are just jaw dropping i never thought facial expressions was possible yet I cant get over how great the facial expressions are sometimes i just leave the game and just look at Narikos face in the chapter selection screen its amazing
Now to go talk about what everybody is totally **** and babying about the games length Is the game short? Yes
Can be beat in one sitting if you have nothing else to do with your life? Yes
It took me about 2 and a half days to beat it and im not really complaining Heavenly Sword to me honestly its like one of your fav movies you can play it over and over and not get tired of it the freaking combos are endless if you really trying to master it Its just a great freaking game i dont see why you just want to rent it im sure sooner or later your going to want it to play again I feel like Heavenly Sword is a game every PS3 owner should have its great from beginning to end its really showing what the PS3 is capable of The game is just pure greatness and as many have said before me since when greatness defined in a length of a game? I have said once before i will say it again gamers are SPOILED This game deserves not less then a 9
