Sega Zone video game system
I see Sonic the Hedgehog playing tennis with Mario on the Nintendo. I mean, if Nintendo knew what was going to happen in the early nineties, then they never would have worried about them as competition.
Apparently, this Sega Zone is actually some sort of Wii emulator that allows the players to do classic video games like Golden Axe, Sonic and Knuckles, Ecco the Dolphin, and 30 other games.

The Sega Zone doesn’t come with the classic Genesis controllers with the A, B, and C keys, but two motion controllers. These motion controllers are good for 16 out of the 30 included classic Sega games.
The company plans to put even more classic Sega games in the future. As I mentioned before, this will be available this summer, and the price will be around £50.
Of course, I have heard that there is already some sort of emulator for the iPhone that will allow a user to play old Sega games like Sonic the Hedgehog. It is called the Ultimate Genesis Collection for the iPhone. This emulator is free, but the games are $3 each. Make your own decision on what is the best value for you.
