I don't remember many surfing games. Jet ski games were kinda big with wave race, splash down, and stretching it a bit, jet moto. And there were more that I'm forgetting.
I want to see more free running games. As much as I liked the feeling of being chased and chasing in Mirror's Edge, I wouldn't mind if a sequel was handled as a racing/extreme sports game. The time trials were what kept me playing.
