If you're trying to give it a realistic feel, do away with the graphics and make it a text based game.
Structure it like an online forum, incorporate a heap of AI chat-bots for realistic interaction and have the player awarded or deducted points or red & green thumbs on a sliding scale based on, the street cred of their posts, creating flame wars with associated wind sports and other kiters, beach PR being affected based on the player's posts, pimping gear, promotion of exotic kiting locations, the successful or not creation of multiple logins and the overall goodness or badness of the player's online persona.
The player loses when kiting is banned at the beach or they're banned from the forum, the player wins when their points/green thumbs and online friends reach a certain level.
Bonus points could be awarded for successful trolling.
