  We reason about possible future development of quantum game theory and its
impact on information processing and the emerging information society. Two of
the authors have recently proposed a quantum description of financial market in
terms of quantum game theory. These "new games" cannot by themselves create
extraordinary profits or multiplication of goods, but they may cause the
dynamism of transaction which would result in more effective markets and
capital flow into hands of the most efficient traders. We focus upon the
problem of universality of measurement in quantum market games. Quantum-like
approach to market description proves to be an important theoretical tool for
investigation of computability problems in economics or game theory even if
never implemented in real markets.
