Are there branches of game theory that look ways of making things more optimal for consumers? For instance if the location of the crowd was unstable it might change the calculus for the vendors. Maybe we just need built-in perturbations to keep equilibrium points from being to predictable.

People acting less predictably...might be something there.
There is a concept of mixed strategy equalibria, to account for games that have probability distributions rather than fixed states each turn.
More parties than two comes with its own issues as well.
Don't know more about it than that
