God of War: Chains of Olympus does not feel like a handheld game at all.  Its every bit as action heavy as its console counterparts.  Chains of Olympus is a prequel to the first God of War.  The controls feel almost identical except for the dodge being mapped to the trigger.  Though sometimes due to the inaccurate nub they can be a little wonky.  Also if you sweat at all the nub gets very slippery.  The graphics are almost of the same quality as God of War which is amazing for being a psp game.  This game would have scored higher if it were not for the last hour of the game.  The Temple of Persephone was as a whole a cheap way to extend a short game.  Room after identical room of fighting pointless battles.  On top of that the last boss fight was good, but if you died the game had to reload, you had to walk up a flight of stairs, and then watch a cutscene again before fighting.  This was very redundant and most game developers know these days to put the checkpoint AFTER the cutscene.  On the whole Chains of Olympus was a great game that I recommend any God of War fan playing, as it does add some interesting insight into the fiction as a whole.
