The aim of this paper is to give, for Nash equilibria, a well posedness criterion which is an ordinal property. This notion is important for games because it emphasizes the fact that player's decisions are expressed by preferences and not by a special choice of utility function. We show that the ordinal property of this well-posedness criterion comes from considering value bounded approximate equilibria.

Abstract
The aim of this paper is to give, for Nash equilibria, a well posedness criterion which is an ordinal property. This notion is important for games because it emphasizes the fact that player's decisions are expressed by preferences and not by a special choice of utility function. We show that the ordinal property of this well-posedness criterion comes from considering value bounded approximate equilibria.
