There are some games I'd really like to be able to share with my kids but can't because of sex and language. Wouldn't have mind playing Fable 2 with my kid, but there's sex and homosexuality in that game, not suitable for my kid at his age. Risen would have been fun to play with him, but again sex and language prevent it.
Wish some of these sex and language 'features' could be filtered out totally via in-game menu options. That way people who want it can have it and those of us who don't want it for any of the given reasons can turn it off.
