All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
We advise you not to buy this game but continue to neglect it and preserve your time which is your real capital that you should invest in what benefits you in this world and in the Hereafter.
Also, we advise you to continue neglecting the mentioned game because there are prohibitions in buying it, as it contains religious prohibitions as you mentioned. Buying what includes religious prohibitions is not permissible in general because the price includes the whole sold item including these prohibitions and we are forbidden from spending our money on what is not lawful. Indeed, what Allaah has forbidden, its price is forbidden whether paying it or taking it.
Moreover, among the religious prohibitions, is that buying pirated copies is Islamically forbidden and you are not in necessity to do that. Besides, this game is not a scientific material that we may say that it is permissible to buy for personal benefit even if it is pirated. Therefore, praise be to Allaah Who enabled you to stop playing that game, and you should continue as you are now. Indeed, there are many other permissible games; for more benefit on the conditions for playing computer games, please refer to Fatwa 86146.
Allaah Knows best.
