  A protocol for considering decoherence in quantum games is presented. Results
for two-player, two-strategy quantum games subject to decoherence are derived
and some specific examples are given. Decoherence in other types of quantum
games is also considered. As expected, the advantage that a quantum player
achieves over a player restricted to classical strategies is diminished for
increasing decoherence but only vanishes in the limit of maximum decoherence.
