All in all this game is not the best in terms of action or adventure, the graphics I found where very PS2 and some of the camera angles made the gameplay very hard as you can't attack when a tree is in line with the character...can you?!?
However it's a very original idea for a game and its great fun when you see half the techniques you can do, but this only lasted for around an hour with me after playing as dialogue is repeated throughout the game (different people saying the same thing) and sometimes weapon commands do not work
If you want a good action/adventure game for the PS3 then go for 'Uncharted Drake's Fortune' it's worth the money as it is cheaper than Assassins Creed.
Take my advice and do not pay over £25/£30 for this game, its nice and long but I think maybe a little too long as the ending was very disapointing for me...let's hope for a better sequel!
