From Postmodern: Talent Tree Compendium:
WHAT IS OGL POSTMODERN?
OGL Postmodern is Big Finger Games’ catch-all title for their line of Modern d20 add-ons and enhancements; but more than that, it is a state of mind.
Postmodern art and entertainment allow that creative imitation of sources is just as artistically valid as faithfully recreating an actual subject and posits that perhaps, given our skewed view of the actual object, imitating the unreal rather than the real is a more successful undertaking.
Therefore, in many cases, postmodern art is based as much on other art as it is on reality, and the rigid “rules” of the real world take a backseat to the demands of creation. We laugh at old movies where the good guys never run out of bullets, but since those movies exist, in John Woo movies we accept that Chow Yun Fat only runs out of bullets when it is dramatically important that he do so. After all, the movie isn’t about counting bullets; it’s about Chow Yun Fat being cool.
Roleplaying games can take a lesson from that.
With OGL Postmodern, Big Finger Games’ stated goal is to provide a mix of authentic cinematic action, colorful and robust character options, precise and flavorful rules, and inspiring and sophisticated storytelling for your Modern campaign.
