My country is infamous for having strict laws concerning violence in games (and in movies, btw).
But you can buy this movie over here when you're 16:

9 songs is not a good movie. It's more an arthouse porn attempt (with some good live music footage between the explicit scenes), but I like the fact that 16 year old teenagers can buy it over here. Just like "Lie With Me" (yes, there are regular American movies with explicit scenes), "Intimacy" and others.
As someone said before in this thread: Sex is always better than violence.
But if most movie directors have a hard time to implement sex in a decent way, how would game developers achieve this as long as lots of their character animations still look like muppets compared to real life?
