Collectibles by Avalon Hill

Advanced Squad Leader (ASL) is a tactical-level board wargame originally developed by Avalon Hill in the 1980s. Over subsequent years, Avalon Hill released many modules for ASL, each containing additional rules, scenarios, and counters. Some of these modules have become collector's items due to their rarity and historical significance.

Several of the ASL modules have become collectors' items due to their limited print runs or special editions.  The game is best summed up by the following quote from a 1996 Avalon Hill catalogue:

“Our crowning achievement, and the ultimate wargame. No other can match its combination of beauty, detail and excitement. ASL is a system based on the original Squad Leader game, but revised and expanded so that ultimately a player can simulate any company or battalion-level ground action in any theater of WWII. Playing pieces (counters) represent squads, half-squads and crews, plus individual leaders, heroes, vehicles and guns. Each ASL module contains eight or more carefully balanced, historically based scenarios — but players can also design their own using the 40+ geomorphic SL/ASL mapboards, numerous terrain overlays, copious historical notes, and thousands of counters depicting virtually every vehicle, gun and troop type in action during the war by every major and minor combatant nation."
