...responsive to a determination that the first player purchased the in-game item, the player profile may be updated to reflect the purchase and the first player may be matched to play a second gameplay session in which the in-game item is suitable to be used.

For example, if the in-game item is a weapon (e.g., an accurate and powerful sniper rifle), the second gameplay session may be selected because the weapon is highly effective in the second gameplay session. Doing so may encourage the first player to make subsequent purchases due to the satisfaction of effectively using the in-game item during the second gameplay session.

Conventional systems further fail to leverage matchmaking processes in other contexts, such as influencing game-related purchases, suggesting group formations, training/identifying non-player characters, and/or otherwise extending the use of the matchmaking process. These and other drawbacks exist with current matchmaking processes utilized in multiplayer video games.
