Multiplayer video games involve multiple players playing using either a single computer system or multiple computer systems connected together. While a first player of the multiplayer game is playing the multiplayer game, the first player's actions are tracked and stored. When the first player quits or stops responding before the multiplayer game has completed, the first player is replaced by a computer-simulated version of the first player that selects its actions based on probabilities calculated from the tracked actions of the first player. The multiplayer game is thus able to continue without interruption or disruption, and the first player's playstyle is preserved.
