The March Madness tournament was famous in the 1990s for giving attendees great ASL tchatkes ranging from personalized leader counters to rare scenario packs (thanks to its association with third party ASL publisher Kinetic Energy); the Kansas City Irregulars seem interested in reviving this tradition (announcing more scenarios to be released at their 2008 tournament).

The main people behind the tournament (and thus presumably any related ASL products) seem to be Dan Best, Paul Works, and Tom Meier.

Commentary:  Perhaps the most unexpected and unheralded ASL release in 2007 was the Pusan Perimeter Pack, a boutique item created by the so-called Kansas City Irregular ASLers for attendees at the 2007 March Madness ASL Tournament in Kansas City, Kansas.  In the 1990s, this tournament was well known for giving out exciting ASL items to tourney attendees, thanks largely to its relationship with third party publisher Kinetic Energy.  The Pusan Perimeter Pack seems to have been an effort to recreate this excitement, though the minimal prior announcements about the pack means that it might not have attracted many additional attendees.  Most people in the ASL community only heard about the existence of this item months after the tournament when a copy of the pack was offered for sale on E-bay.

The publisher claims that only 50 (numbered) copies of the pack were produced, a claim that, if true, would make the Pusan Perimeter Pack one of the rarer and more collectible ASL items. 

The six scenarios are all set along the Pusan Perimeter (the last-ditch defensive perimeter held by the US and South Koreans following the North Korean invasion until they broke out of the perimeter in the wake of the Inchon invasion) from July through September 1950.   They appear to be tournament-sized scenarios.  Because the pack is billed as a "teaser" (presumably for the long-in-the-works Korean War ASL module), it is not clear if the scenarios were fully playtested.
