• Nintendo and Best Buy have partnered up before, to allow fans to play select games at demo kiosks prior to release, and it seems the tradition will continue with Super Smash Bros. Ultimate. Ten United States Best Buy locations will be setting up demo units later this month, and into October, where you'll be able to try out the game before its December 7th release. If you live in California, Washington, Texas, New York, or the other listed states, you might want to see if one of the events is near your area. Small prizes will also be given out to those that play the demo.
