The Innoventions pavilion at Epcot is still around, but it's a bit blergh in 2017. In 1994, though, it was the future, and a big part of that was getting to enjoy Sega in its prime.
Which we can all do now, thanks to this video. It was shot by iretrogamer's dad during a holiday in '94, and features a nice big walkthrough of Sega's immense (and now all but forgotten) presence at Innoventions, showing off new games, hardware and arcade cabinets, all of which kids could just walk up to and play. You could even try out the Sega Channel, the Genesis' downloadable games service.
The announcement of the Xbox streaming service briefly took me back to the '90s and to the Sega Channel, an invention so great it basically erased most of my memory of 1994 as I entered a state of pure bliss closest to what David Foster Wallace described in Infinite Jest.
