Well a few things to say here, firstly this is more of an issue with one guy, as has been said before.
Then ironically, in refusing to create an R-18+ rating the people in charge of these things are actually exposing more violent games to children at a younger age than those in the US and such places.
See aside from the odd refused classification (Which I might add seems to be completely arbitrary and has little to do with actual content) most of the games get through unchanged with an MA-15+ or an M-15+ rating where in america they would have gotten an R-18+ (Or do you guys call it T-18? I forget). So the average australian 15 year old actually has access to more violent content in games than the average american one.
As a whole honestly australia seems to be more laid back when it comes to these things than america, it's just that we have some odd bureaucratic choke points that we can't seem to get rid of.
Another example is the ratings bored continued banning of the odd (again arbitrary) film that contains depictions of nudity despite having absolutely no problem with hardcore X-rated porn movies which in any case have content far more gratuitous than any non-porn movie.

Of course the gameplay is the most important part but if devers would respect this then there would not be such a huge pile of mediocre or bad games. Now to the point of gore as selling point. Just look at recent games on your favorite game news site or whatever place. Many present themselves better or buy-worthy because they have as much gore, violence or sex possible. Why do they need this? Because the game itself is a run-of-the mill mediocre FPS/RPG/whatever. Instead of innovating in gameplay they try to make as much gore/sex/violence as they can. But the truth is that a good game with good gameplay, catchy story and god challenges does not require gore everywhere. In fact the best game I know has little blood or gore but is one of the best selling games every. This is why I say this should be taken by game devers as a sign to rethink this more-gore=better-sales crap they have going on.
I enjoy the odd bit of gore because it's simple mindless fun, that's it. Nothing more is needed sometimes. I also resent you citing left 4 dead as a game barren of interesting gameplay. Left 4 dead and others like it (Like gears of war) have quite advanced competitive multiplayer in them and are simply topped with a bit of gratuitous fun that happens to come in the form of buckets o' blood.
Granted this isn't everyone's cup of tea, but I can assure you that if they were as lacking in gameplay as you seem to think they are they wouldn't have spawned such successful competitive scenes where so many other games have failed to.
