Tony Hseigh: "I remember when Gran Turismo 5 first launched, there were some rumors on various forums of an update to the game (or a spinoff) that would add open-world driving to GT5. It sounded too good to be true, and eventually, all us sim racing fans realized it was just a pipe dream.
Then the VGAs hit later that year, and we were given the Forza Motorsport 4 teaser trailer. The trailer was packed with live action shots from the show Top Gear, and eagle eyed viewers noticed that there were some quick shots of night racing and off-road racing. Again, the rumor mill started spinning, and we all thought Forza 4 would have day/night transitions and off-road racing. Again, we were wrong."
