A game
monetization strategy for encouraging player spending by splitting the player base into smaller isolated groups (often servers) that cannot interact with each other within the game, especially in the context of pay-to-win and gacha. Whales will find it easier to top leader boards due to the smaller amount of
competition, and non-whales who are surprised to find themselves on the leader boards will feel pressure to spend money to keep their position. Additionally, if casual players begin to lose interest and depopulate servers, low-population servers can be merged (usually without notifying players) to prevent whales from realizing that they are
spending money on a dying game.
