Wasn Combat Mission originally based on Avalon Hills Advanced Squad Leader?
Combat Mission (CM) has its roots in an earlier project called Computer Squad Leader (CSL) which was based on, but not a literal translation of, Avalon Hill’s Advanced Squad Leader (ASL). But Big Time Software and Avalon Hill parted ways as work began on CSL, so Big Time switched gears and created an original game system from scratch called Combat Mission, which, besides the topic, has nothing to do with Avalon Hills classic board game.
