Remember the EyePet ? Well, this is kinda like a really advanced version of that on the PlayStation 4.
Sony's PlayRoom will allow you to interact with your TV and living room in a way you've never seen before. It's a little creepy but at the same time…kinda cool.
Here's a tech demo for the aforementioned "game" (is it really a video game?) and it shows one person and then two people playing around with a slick, futuristic virtual presentation. Toward the end, they fill the floor with these cute, friendly little martians, and it shows how you can draw something on the Dual Shock 4's touchpad and then immediately bring it to life. Just remember that you would need the PlayStation Eye for this, and that's an additional $60 as it won't come packaged with the PS4.
I'm not that into this kind of stuff, but that's probably just 'cuz I'm old-school. The new generation will probably love it.
