Gravitation Astrometric Measurement Experiment
  The Gravitation Astrometric Measurement Experiment (GAME) is a mission concept based on astronomical techniques (astrometry and coronagraphy) for Fundamental Physics measurements, namely the \gamma\ and \beta\ parameters of the Parametrized Post-Newtonian formulation of gravitation theories extending the General Relativity. The science case also addresses cosmology, extra-solar planets, Solar system objects and fundamental stellar parameters. The mission concept is described, including the measurement approach and the instrument design.
