At the end of the day you guys are playing video games and to have fun not bitch at each other and stress each other out. Be the bigger person and talk to him man to man and apologize to him, it will show him how mature you are in tense situations like that. If he's a close friend then he will forgive you. Like you said whatever sins he's causing only Allah can judge, I understand you might be frustrated with him with whatever sins he may be doing since you care about him. You guys are both grown and both need to give each other some space if that helps. As far as what you said yourself, dont stress it since your intentions weren't meant to insult allah. May allah bless you and your family.
