I've seen ORBX "PeopleFlow", where people walk around. I thought: Mmh, you have seen this before...
Today, I remembered the two games "MidtownMadness" and "Driver: You are the wheelman".

There also people walked around:

I only own "Driver: You are the wheelman", and in the internet are no pictures of MidtownMadnesses people.
Both games were out before the year 2000, and "MM" (MidtownMadness) was done by Microsoft.
Why Microsoft didn't used the people in big cities like New York etc.? Maybe for the space on their hard drive... or they forgot the game.
For me it is crazy, that it took so much time to teach the people walk again... So "PeopleFlow" is not new, it's simply taken out of a box with old software.
