I advise my friends not to play Crash 3, is that right?

I think if you have a good relationship with your friends, I think it is right for you to advise him not to make kryptonite, because you are thinking of him from the standpoint of friends and will not affect your friendship. Of course, whether your friend listens to your advice or not is your friend's business. You tried to persuade him, hoping it would help you.
