We examine the classical contents of quantum games. It is shown that a quantum strategy can be interpreted as a classical strategy with effective density-dependent game matrices composed of transposed matrix elements. In particular, successful quantum strategies in dilemma games are interpreted in terms of a symmetrized game matrix that corresponds to an altruistic game plan.
