Some of the preloaded titles include Avatar, Uncharted 2, Assassin's Creed 2 and Final Fantasy XIII (Already released in Japan; March 9 for the rest of us - and I can't wait!).
I've flown through HK International before, and I can attest to it being the best airport I've ever flown through. With a huge shopping center and food court (plus trams that take you every which way in the entire airport very easily), it's already so good it doesn't even need this. But I'd be happy to take advantage of it if I found myself over there again.
