John Riccitiello, EA CEO has claimed in an interview with Industry Gamers that Battlefield 3 is "more authentic" than the competition. Riccitiello in a complimentary interview said that the head to head clash of the Modern Warfare 3 and Battlefield 3 would be good for the industry, he did however offer a not so favourable opinion in regards to authenticity:
Riccitiello also threw Activisions Call of Duty Elite paid service in to the firing line and compared it alongside Battlefield 3's own solution Battlelog; which is to be offered freely. Scoff... who needs authenticity when you have a bouncing Throwing Knife in your arsenal!
