The out-of-engine CGI cutscene in FCoB is at the end of T12, and anytime someone posts it to youtube, SE sends a C&D to have it taken down. One video managed to slip through by having it embedded at the end of a bunch of other stuff. It's not hard to find, but I'm not going to link it here. I won't deny that it's pretty darn awesome looking, but personally, I don't feel it added much to the game or the story being told. Especially since what actually happens in the scene has to be explained to you in a normal conversational CS that follows it.
In short, the out-of-engine CGI cutscene is totally extraneous and could have been left out without changing much, if any, of the dialogue and none of the plot would have been lost. I would have honestly preferred if they had taken the money they spent on that CGI CS and instead used it to improve the cinematography and overall quality of other story cutscenes in 2.4 and 2.5. Though, in my opinion, 2.5 did have a few good ones near the end.
