I remember Sega Channel. In 6th grade, my friend had it. I didn't grow up with BBSes and had only learned about the Internet the year before (from the same friend), so the idea of downloading games was pretty wild. The service was way ahead of its time.

IIRC, it was $15/mo. There was a monthly or weekly rotation of games, including some pre-releases. I think at one point we played Vectorman when it was still new in stores or possibly just prior to its official launch.
