Defiance, first and foremost, is a console MMO, and for that purpose it is going to be brilliant. It’s a strong shooter with some very arcade-y takes on the MMO genre. The lack of any adherence to the “rules” of the MMORPG means that Defiance seems far more accessible that the average MMO, and with a single purchase, no subscription, I can see it being a big hit. It might actually do the impossible and bring the MMO to the console masses. The PC version, then, is almost certainly at risk of becoming little more than a distant cousin, especially once you take into account how many similar games are already available to the core MMO gamer.
