Just Adventure's Randy Sluganski reported that In Memoriam had reached 85,000 registered users by the time its European sales hit 35,000 units, and that certain registrants were based in countries where the game was not available for purchase. In Memoriam nevertheless became profitable and "a hit" for Lexis in Europe by mid-2004, according to Sluganski, but profits lost to piracy slowed the developer's growth. The game reached 100,000 registered players by September 2004, following its release in the United States.
