Resistance 2 vs Killzone 2

Two of the biggest FPS (First Person Shooter) on the Playstation 3 at the moment are Resistance 2 and Killzone 2. One of the things that make these titles good to compare are that they are both Playstation 3 exclusives. I was originally going to compare Killzone 2 with Gears of Wars 2 (an XBox360 exclusive) but since their is enough fanboy debates on the internet I thought it would be better to compare exclusives for one system. Resistance 2 has been out a few months now and has already gained a nice following, it is the follow up to another Playstation 3 exclusive, that being Resistance: Fall of Man and it follows on from where Resistance: Fall of Man left off. Killzone 2 is due for realease at the back end of February 2009 and is surrounded by more hype than Metal Gear Solid 4, if that is at all possible. Unlike Resistance 2 though it is not a follow up to a Playstation 3 exclusive but it is a follow up to a Playstation exclusive as the last Killzone was a Playstation 2 exclusive.
