What counts as 18+?

It has become so common to see violence that I'm not even sure what falls into the "extreme violence" section anymore...

I'd say that killing someone should be extreme violence (as in, death is definitive - that's the extremity of pain) but it's really depending on the local culture.

I remember having someone commenting on my game, saying that a sex scene that happened was disturbing and unnecessary (even though they're 32px sprites and their bottom half is under the blanket). What amazed me is that the commenter didn't say a word about another scene where you slit throats of sleeping people.

I'd have thought that scene would have been disturbing...

I guess it's a cultural thing.

So, no definitive answer for your question. As some have said, each country has different views on the subject.

Do your game as you think it should be and don't bother about rating, unless you're aiming for a specific country.

That entirely depends on the country, and the media. Videogames for example, have different ratings than movies.

This totally! In Europe, most people would not flinch mild nudity or natural nudity. Sex scenes obviously rate higher, but German or French or even Nordic movies show great bunch of butt cheeks without people batting an eye.

While the forums are 13+, it does not mean you cannot publish more mature content in here. Just make sure you put clear disclaimers about your content in the thread. Obviously you should not showcase those bits in the thread either. The game is also most likely geared towards international public, so going by the US/Canadian standard is probably quite safe. It is quite strict, but still reasonable.

I am sure there are guidelines what each class could contain. Better be safe than sorry and ask someone else rate it parallel for you to get unbiased opinion on top of your own.
