Games do cheat their players all the time, but it is most often for the sake of the players and their human flaws. These lies are told by the game designers to help the players enjoy the game as it is meant to be and give them the best possible experience. Often the goal is to keep them entertained, but sometimes the goal can be more greedy i.e.. in the case of keeping people spending money on gambling or in F2P games. As with many aspects of design, these tricks can be used both for good and evil, so it’s up to the game designer to realize their power and use their lies ethically.
