To be fair, if a game gives me the option to nuke, like Starcraft or Red Alert, I be nukin’ too!

I don’t even know what an AI PC is.

Sarcasm can be conveyed non-verbally. Through facial expressions, gestures or situational context for example. The core concept is not bound to specific languages but to the social/cognitive ability of the communicators, I’d say. Young children have a very hard time with sarcasm, regardless of where they’re born.
