Talking smack to CVG, Activision marketing director David Tyler criticized the competition as “failing to inspire” when it came to the first-person shooter market and Call of Duty 4 in particular.

“We’re pleased to have Call of Duty 4 leading the way in the FPS genre, with recent launches such as Army of Two and Rainbow Six: Vegas 2 failing to inspire,” he said to the publication.

The game has sold big in both North America and Europe, and is currently selling well enough in a little country called Japan. The recently released Variety Map pack is also said to be doing good business on Xbox Live (a PSN version is coming).

“Call of Duty 4 has been a phenomenal success for us and reflects Activision’s commitment to creating truly ground-breaking games,” he continued, saying that quite a few “normal” gamers as well as a number of celebrities are also joining in on the action.
