OK... Good news, but some things though... Did they think this through before writing it?
document says. "Sexual activity may be realistically simulated. The general rule is, 'simulation, yes - the real thing, no'."
Now, feel free to point it out if I'm forgetting something here, but unless this was lifted wholesale from the film classification guidelines, this particular statement makes no sense whatsoever.
With a handful of exceptions owing to Full Motion Video (Which nobody really uses much anymore), video games are 100% simulated by definition.
This means 'the real thing' is a meaningless concept when applied to computer games.
Ergo, this comment implies pornographic computer games can get an R18+ rating, while otherwise equivalent sexual content would have an X rating (or be banned altogether).
That's... A very weird statement, to say the least.
