I play this game and of course it has all genders. I have made a few friends on there, and a few friends who are boys. Keep in mind that I don't know them in real life. Is it still haram to talk to them?
Salam, Being friend with some one has a psychical influences in your mind. If being friend with some one is limited at a group, it might not be false, but chatting with some one or talking via internet and ... that has effects like real speaking, you must avoid. All things refer to yourself, if Islam makes a limitation it is for you to have a healthy thinking and life. Fi Aman Allah
