Praise be to Allah.
We are appalled by what we have seen of clips from this game – especially in the second and third versions, and there is no evil action or immoral deed but it exists in this filthy game. It also contains music, dancing, wanton display of beauty, drinking alcohol, complete nakedness of men and women, illicit relationships between the sexes, kissing and touching private parts; it is so bad that there is even committing fornication completely, which is not found even in ordinary movies! And all of that is with the excuse that they are animated characters, as if the one who watches it will never be affected by what he sees and that it will never be provocative. The game includes “university life”, “nightlife,” and “New Year holiday” in which there is dancing, singing, kissing and illicit relationships, and Santa Claus appears to distribute gifts to the children. We do not know, by Allah, how any Muslim could accept to allow his daughter or his wife or even his son to play this evil game. This is natural in the life of Western families, who has deviated from all decent behaviour and noble characteristics, and there are those who want this to be natural in the life of Muslim families too.
We have previously discussed the prohibition on looking at cartoons that include nakedness and permissiveness, in the answer to question 167710.
Based on that, it is not permissible for a Muslim to upload this game or play it, and it is not permissible for him to allow any member of his family to do that. Whoever does that is neglecting his flock for whom Allah, may He be exalted, has made him responsible and he is failing in his duty to advise them and to pay attention to their upbringing, behaviour and attitude.
We have issued a fatwa specifically about pornographic cartoons, their real nature, the danger they pose, and the ruling on them. See question no. 115149
And Allah knows best.
