Great video! Although I felt Jero123's question was awful. I mean really. For one, the question itself generalizes pretty much everything ever, and makes it hard for DB to answer, but what is worse, is that it is filled with assumptions! Games more 'casual' then ever before? By who's count? EVE online easily trumps pacman and pong in complexity.
What a waste of a question. Especially since we already know the answer to it. What is the defining attribute of the Elite series? Accessibility. Elite is quite easy to fly, at least until you have to dock. Frontier was exceedingly easy to fly, until your autopilot was destroyed and you started flying 'manual'. The Elite games have always been about accessibility for all, except for having a rather high skill ceiling as you learned more about the game, and realized you are not half as good as you think you are.
Seriously, what an awful question. :|
Great video otherwise! and excellent art behind Mr. Braben's head! Loved the people boarding the passenger ship.
