What is the ruling on profiting from designing electronic games that rely on monetary payment in exchange for features or faster progress, and is it permissible for a player to sell his account for real money, and is it permissible for me to take a commission on that?

If the game is free from religious prohibitions, there is no harm in playing it or spending money on it. However, one should not overindulge in it, and it becomes forbidden if it leads to neglecting religious duties. It is permissible to purchase features that enhance the game's enjoyment, to transfer one's achieved position in the game to another person, or to mediate such a transfer, even for a fee. Nevertheless, it is advisable to avoid these activities, as they often lead to wasted time and the dereliction of duties.
