Going to have to disagree with the OP on this one, but I agree that the things you mentioned don't increase the maturity of a game. The whole concept of maturity is nebulous anyways, especially in entertainment. If you want to apply your criteria to modern entertainment standards, there are very few mature things made anywhere.
The mature piece of entertainment ends up being few and far between, and it may not always be a complete package. Case in point: the card collecting nonsense from the Witcher 1 was juvenile, but several elements of the story were very well written and had a very *mature* moral ambiguity to them. If you look past some of the more base elements in certain games, they can be very mature- but that leads to my final point:
Games are interactive. How you play them determines your experience. There is a gap between someone who jumps into MGS3 with a rocket launcher and just blows up everything in sight, and a person who carefully and painstakingly sneaks through using tricks and cunning. Games are mirrors to ourselves and the maturity comes from how you play them- I once read an article about some parents who let their kid play COD4 only after reading the Geneva Conventions and playing by them. This stuff, in my opinion, makes the difference.
