Maybe I shouldn't have mentioned Bioware - I only did that to show how well voice acting can manage different options, which otherwise would be seen as an obstacle. As I pointed out earlier, the choices would be on par with what they were in VII - Not every sentence, far from it - but on occasion you would get to make a choice that would alter a subplot slightly.
The best example I can think of is how, as Cloud, Tifa asks if you slept well. One of the options is something like "Next to you, who wouldn't?", which increases your chances of having a date with her later on (if I recall correctly). This didn't change the overall storyline, but did change part of what happens to that particular play-through. That's what I'd like to see more of, as they simply don't do anything like that anymore that I can think of.
