Actually, the idea isn't so far-fetched; it aims to integrate the powerful social aspect of staying fit with a game that lets you compete against others in a massively multiplayer environment. By completing certain "micro-physical challenges" throughout the day, a player can earn achievements while becoming healthier. Known as UtiliFIT, the game is an upcoming MMO created by former CCP North America president and former White Wolf CEO Mike Tinney, who has secured "one source of seed round funding" from BVM Capital and hopes to release an early playable beta version later this month.
