I am referring to the feature of 4 players splitscreened on the tv, while an additional player is on the GamePad. Also they could have let one player play on the GamePad and one player on the tv for online modes.
This feature was utilized in Sonic & All-Stars Racing Transformed and would have made much more sense for MK8. Considering MK8 is a game that gathers friends around the tv just waiting for a turn to play. Instead of cycling through 4 people, you would have 5. Framerate drops should not be a factor, it would be well worth it to have an additional human player.
This isn't a deal breaking omission and I do not raise this topic to nitpick. I mention this because MK8 is one of the supporting pillars in Nintendo's strategy to revitalize the momentum of the failing Wii U platform. While MK8 highlights graphical prowess with vibrant track environments, the most extensive online features yet in a Nintendo game, and all around more balanced/fun karting gameplay, it is yet another Nintendo game that is unable to effectively integrate the platforms core innovations. These core innovations are present and in replacement of excellent features on other platforms (powerful hardware, new tech), but we only see these innovations (secondary screen functions) with a handful of generally forgetful experiences like Nintendo Land.
"Mario Kart 8 made my kids put down their iPods, and that's worth celebrating."But they could have really driven this phenomenon further. I doubtfully hope this can be included on a DLC pack or update. Nonetheless a missed opportunity to immediately show a crowd of gamers that only come back to Nintendo to play the MK and SSB franchises why Wii U exists the way it does.
