We examine games played by a single large player and a large number of
opponents who are small, but not anonymous. if the Flay of the small
players is observed with noise, and if the number of actions the large
player controls is bounded as the number of small players grows, the
equilibrium set converges to that of the grime where there is a contin
uum of small players. This paper extends previous work on the negligib
ility of small players by dropping the assumption that small players'
actions are ''anonymous.'' That is, we allow each small player's actio
ns to be observed separately, instead of supposing that the small play
ers' actions are only observed through their effect on an aggregate st
atistic. (C) 1998 Academic Press.
