"Knock off" is a gross understatement and a very narrow view. It's an FPS first with a (so far) valiant effort to add the MMO trappings of titles in that genre. Consider for a moment adding the gameplay, fidelity and variety of the Halo franchise to an MMO and then making it available to two different service providers across 4 different platforms whilst wrestling a multinational publishing company. Now consider yourself a narrow minded, spoilt ass hat and the circle is complete.
