The problem is not 'realism' in video games, the problem is that video games, like comic books in the 90s, have little or no idea of what is realistic.
What is passed off as realistic in games, as in comics, is usually grim 'n gritty juvenile rubbish, an angst ridden teenager's view of what is real or mature or 'grown up', and is in any case utilised primarily as a selling point rather than out of any genuine desire by the developer to tell a 'mature' story.
Realism is often highly overrated. I think a rape/attempted rape scene is inapropriate in Tomb Raider, in the same was as it would be inapropriate in an Indiana Jones movie. Realism has no place in the genre of high adventure.
If CD want to shift Tomb Raider from high adventure to gritty violence and torture porn then let them do so, but it insults our intelligence when they try to excuse the unrelenting sadism and pointless brutality of the reboot as more 'realistic'.
