Hyperbole can be venomous to a review's credibility. Any insightful merit which a video game critique may possess seemingly goes out the window as soon as the reviewer starts dropping bombs like "best game ever" or "literally mindblowing" or "it will birth you anew in its magnificence." Perhaps it is because we've all heard these phrases -- save for that last one -- so many times that they've lost their currency with us.
Rest assured, I'm not being hyperbolic when I say that Batman: Arkham Asylum is unquestionably the best licensed game I've ever played. At the end of the day, however, that's a fairly low hurdle to clear -- it better reflects the game's quality to say it's one of the best stealth-action games ever made, and easily the best video game 2009 has had to offer thus far.
