1. Film, as a medium, has a much longer history than video games. There is typically a richer background to draw from and a wider array of techniques to communicate subtleties. Video games typically get their point across through game mechanics. The medium still has a long, long way to go to be able to mechanically deal with something like rape in a way that is anywhere near respectful. I'd hoped to go as long as possible before having to talk about "rape culture" and video games, largely because the term seems to be misappropriated a great deal of the time, but while there is a lot of charges laid at Hollywood's feet for phallocentrism, it has nowhere near the same history of sexualized violence being directed at female characters (and players) that the video game industry does, as well.
2. You're quite right, and I can count on the fingers of one hand the films that have even ventured into that territory with male protagonists. On the one hand, it was framed as a deliberate response to the elaborate traps previous Bond villains have used, and while I was actually a little weirded out at the decision to use that sort of sexual violence in what seemed like a joking way, it was still nullified in a way that rape could never be, since nothing actually comes of it. Aside from a throwaway line, they don't have to deal with any of the consequences and Bond's virility is re-established in a few minutes. If it were a female character, that kind of shit would have taken on a completely different tone.
3. Hmm. That's an interesting interpretation. The definition I'd presumed they were using was that psychopaths can form relationships with others, but typically don't value them to any great degree.
