Does one who produces a game containing idols and worship of other than Allah become a disbeliever, requiring repentance?

It is advisable to disregard whispers (waswasa) and refrain from asking about them. None of what was mentioned constitutes disbelief (kufr). Not every doubt concerning the disbelief of a disbeliever is considered disbelief. And whoever declares a Muslim a disbeliever unjustly does not become a disbeliever thereby.
