Believing in God is fine if it gives you peace the problem comes when you try to force your beliefs on others so just let those who play Videogames and watch anime chill as their not going out and hurting people which would be a worse sin
I don't even play videogames anymore. It's all a waste of time, even the so called "good games". The best Service you can do is to Keep your thoughts on God. Keep God in mind every minute. neem karoli baba
