Nintendo has released all the cup and track names for Mario Kart 8, along with little video snippets of each track. Or you can watch this video by YouTuber Nintendomination that takes all the video previews and makes on giant 34-minute long video to save you the hassle.
Plus there's a video preview of all the playable characters too, along with a look at how, uh, lame the battle mode is now. Battle mode looks to take place on courses, which seems like it'll make the versus stuff more tedious than fun.
