Game Systems, Inc. (GSI) first appeared on the Play-By-Mail horizon 15 years ago with the ORIGINS Award-nominated game "Earthwood". Since that time, Game Systems has added a variety of games to their PBM stable, including the multi-award-winning Middle-earth Play-By-Mail. GSI employs the latest in PBM technology to create game systems that ensure absolute accuracy and fairness. All of GSI's games are close-ended. This means each game has a definite set of victory conditions to strive for and a definite conclusion. Games range in depth and complexity, as well as the number of opponents faced, so that you can choose the level of challenge that is right for you. While all games are fully computerized, you do not need a computer to play.
