What about the context of flying a commercial airliner into a skyscraper?

Moussaoui enrolled in a flight simulator training course at a Pan Am facility near Minneapolis, Minnesota. Pan Am’s Minneapolis facility used flight simulators only, and the training there usually consisted of initial training for newly hired airline pilots or refresher training for active pilots.

It's a Cessna rather than a commercial airliner, but slamming a plane into landmark buildings was not tabo or out of the ordinary pre-9/11: https://youtu.be/ssig3LUCwng?t=4m35s.

Indeed - Tom Clancy wrote Debt of Honor long before 9/11, and Rainbow Six long before COVID.

Again, context. That’s actually a training course. And a plane is mostly computerized. So it makes sense to not train for emergency situations up in the air in a real plane. If Counter-Strike were used for actual training, and maybe it was somewhere, then I’d agree this breaks the rule. But I would never say that making a map means wanting to plan something in real life. It just doesn’t mean that, even if it looks that way. A game like CS is generally not actually a training simulator, it’s just a way to waste time with friends, etc. You don’t actually get any real world feedback or exercise or anything. I would argue actually playing paintball at school would be riskier, though… it also sounds like fun. Maybe it’s a question of harm or intent?
