1. A computer-implemented method to recommend objects usable at virtual locations in a virtual world based on frequency of use of the objects at the virtual locations, comprising: monitoring the use of a first set of virtual objects by a plurality of avatars at a first location in a virtual environment; defining, based on the monitoring, a subset of the first set of virtual objects that are used beyond a first predefined frequency threshold at the first location, wherein the subset is less than the first set of virtual objects, whereby the subset of the first set of virtual objects represents virtual objects used with relative frequency at the first location; detecting an arrival of a first avatar at the first location in the virtual environment; identifying a first virtual object, in an inventory of the first avatar, as being in the subset of the first set of virtual objects; generating, based on the first virtual object being used at the first location by the plurality of avatars at a first frequency greater than the first predefined frequency threshold, a first recommendation for the first avatar to use, at the first location, the first virtual object, wherein the first recommendation is output for display; identifying a second virtual object of the subset of the first set of virtual objects, wherein the second virtual object is not present in the inventory of the first avatar; and generating, based on the second virtual object being used at the first location at a second frequency greater a second predefined frequency threshold, a second recommendation for the first avatar to acquire the second virtual object, for use in conjunction with the first virtual object at the first location, wherein the second recommendation is output for display.
