The Sega Channel was by far the best accessory/add-on of that era. No contest. I remember waiting for the 1st of the month like I was waiting for a gov't check or something. My cousin and I played it morning, noon, and night. Those are seriously some of my best memories of gaming as a kid. We played Skitchin', MK3, Vectorman. I will always love my mother for getting that for me.
