                       "Anatomy of Games"


In evolutionary game theory we characterize the pair interaction
by the payoff matrix. We start the general analysis of such interactions
with the symmetric two-strategy games, because in this case a
potential can always be derived, which guarantees that these
systems are equivalent to Ising-type models and, using a proper
dynamics, the results of statistical physics become applicable.
We demonstrate that if the payoff matrix is cast in a vectorial
form, we can choose a set of basis vectors/games that allows us
to identify a part of the payoff that depends on ourselves, a part
that is due to the partner, and a coordinative component of the game.
In the case of more than two strategies (or the indistinguishability
of the partners) there might be a deviation from potential games
due to the presence of a cyclic game (like the rock-paper-scissor
game), which, together with the symmetries present, has characteristic
consequences in spatial models.
