This is a cool idea, but even more than playing it and learning about NYC, I'm curious to know how you built it, and where the data came from.

An explorable Manhattan built from real map & transit data. Ride any subway, bus, or bike along its true routes & stops, or take helicopter mode and fly above the city to explore.

Walk up to any building's address plaque for its story Wikipedia info & link to historical photos from Old NYC.
