We compute the "equilibrium" play that would maximize joint payoffs if incentive constraints could be completely ignored.

rel_first_best(g, delta = g$param$delta, ...)

## Arguments

g the game object The discount factor additional parameters of rel_spe

## Details

Note that we create the same columns as for a spe, e.g. punishment payoffs v1 and v2 that would arise if every action profile could be implemented as punishment. This allows to use the same functions, like eq_diagram as for equilibria.
