At last, my multiplayer experience on Wii U really begins. Mario Kart Wii got a ridiculous amount of play for several years, so I'm looking forward to getting the gang together and karting it up again. Yeah, at the end of the day, it's very familiar, but it still looks fun, and I'll take it over a simulation racer almost any day of the week.
Obviously, the whole hovercar/hoverbike mechanic is the main new hook for Mario Kart 8. I wonder how driving upside down and such will affect the overall feel of the racing. It's not totally clear in the trailer, although it was cool seeing karts racing on either side of a single vertical road.
