Edit: Okay, it's starting to get crazy in here so let me say a few things. The title was just to draw your attention. Sony didn't do everything first but they did some things. Well from what i know. Enlighten me if you will.
I found these things and i thought it was interesting that Sony did do a lot of things first, it only became succesful after the Wii came out.
This is an exercise game or whatever for the Eye Toy.
I found this in the thread about the motion controle Sony is doing. But i think it is more the people who are working on it that have been doing it for a while not Sony. Because I think Sony came in and just wanted their product.
It seems Sony does everything first lol I guess it wasn't a hit though in that time.
