This project is interesting because when a game economy is implemented in the game, the developer can always give the player the opportunity to influence this economy (discounts, sales, various mechanisms perceived by the player as a purchase of something cheaper). Prices under such a model are initially overstated, as a result, when the shares are launched, the player believes that he receives a discount. Here the principle works: the player can miss the opportunity to use this action. It is said that this is a unique proposal, and if he does not use it, he will lose it. Here, attempts begin to give the player a slightly different game: turn it into a casino. The excitement of winning, based on greed, always works and failsafe. If the player is given random mechanics (dishonest ☺), we will get pretty interesting results - players spin roulette, players pay and forget about the game a little. At the same time, their original purpose was to get a thing or game currency, which is played out in these mechanics. Only when we receive these items can we hope that the player will return to the game.
