  In this report our main attention is focused on the problems which can be
solved at Photon Colliders naturally but are hardly solved at LHC and e^+e^-
Linear Collider: The New Physics - new particles, new interactions,
supersymmetry, Dirac monopole, extra dimensions... SM and the case of a
SM--like scenario - EWSB, Higgs bosons, anomalies in interactions of gauge
bosons, QCD, Pomeron and odderon... By-product: Production of light Goldstone
particles from region of e\to\gamma conversion.
