Systems and methods for dynamic inventory control for player-to-player exchanges between users interacting within an online gaming platform are disclosed. Exemplary implementations may: execute an instance of the game; monitor user-specific in-game actions of a user; determine in-game objectives based on the monitored in-game actions; receive information representing virtual items available for exchange; determine metric values representing usefulness of individual virtual items regarding the in-game objectives; and present the individual virtual items such that more useful items are presented more prominently.
