Ice Ice Outpost has the jumping between tracks, the pretty devious shortcuts, and some really great music though. Mute City is the best though, followed closely by Dragon Driftway.
I picked this game up with my Wii U that I got a few months ago. It's absolutely amazing -- my son really enjoys it as well. (I hope I'm not breaking some bump rule I don't know about!)
No revival rule here. Bump to your heart's content. :P And you should add your NNID to your profile and add me so we can play Mario Kart!
I wonder if we'll get any more DLC announced at the E3 event, or if they're done with MK8. They've done a great job keeping the game relevant up to this point.
I think they're done with Mario Kart 8. More DLC at this point would be ridiculous. They should put their efforts towards Mario Kart 9, or what I think it'll actually be: Nintendo Kart!
Easily the best Wii U game in my opinion. I've spent a LOT of time playing it, online and getting gold in all of the cups too. The DLC is fantastic, every last track and overall I'm so happy I got it. It really opened up the world of Mario Kart for me which makes me very happy.
