Project Gotham Racing 4 has the video game version of the question, "Is it real or is it Memorex?" They've created a split-screen video of the latest Gotham racer next to actual hi-def footage of the live cars churning through the streets of New York City. When it comes to the car scenes, even when you know which one is live and which is video, there's still the occasional flicker of doubt. Watching it, it's hard to believe we ever got excited about a game called Pong.
Thanks for the tip, zizzy!
