Insomniac has really done with this...
It was the very first one that I got for the PS3 and boy was I impressed!
The gameplay was amazing, I think the story line was really good and the grapics... don't even get me started. If you shot the glass in the windows it actually look so real. The blood spatter of the Chimera was amazing as well. Once you had killed a Chimera, if you zoomed in with your gun it look so real. I have completed this game on easy ans medium but not on hard as it is so much harder. The online version of this game is ok but I don't really go on it that often...
Apparently there is a sequel to the game called Resistance: Rise of man that is coming out in 2008 but not much is known about it so, who knows?
