it was a huge flop, and its not that much older than a 360, as it was released near the end of the ps-2's life (maybe 3 years before 360 if even that)
The SEGA activator was for the SEGA Genesis, a plastic ring you set on the floor it used ir beams in a way that it could detect you punching kicking and a few other things like stooping or jumping, it had its moments where it worked fine then others it would go nuts
I have not had the chance to use the motion +, most of my buddies with Wii's havent played them past the first few months of ownership
