I like the way the intros and outros are getting stranger and crazier as the series progresses. One day you will hit a wall though, where you will have to do something so crazy it cannot be beaten.
As for the topic, I cannot say I really noticed that they kept talking about the fun factor, but then again I was watching the video thinking how much fun it is going to be to play it, so I guess the message still sunk in. I definitely agree that the similarities between movies and triple A games are beginning to become glaringly obvious, I think out of the last ten "big" games that I have played, only around three felt like the game actually had some passion put into it, a lot of the time it felt like a sequel for the sake of a sequel.
Unfortunately as long as the games sell, certain developers really won't care, they get the money and that's what matters to them. While a lot of people on gaming websites and forums will complain about the games, the fact the numbers say people still want it will ultimately sway them to stick with what they are doing.
