I got gold on all cups in 150cc. Feels good mang. Also played a shitload of online, which is great. But I hate to be right about one thing: no single-player Versus sucks. I'd love to play just Bowser's Castle, against opponents with items, but I'm stuck playing through half of the Special Cup first, or going through god knows how many races online before my vote is picked.
I swear, Nintendo is like an autistic genius, brilliantly talented but unable to grasp social norms. Here you have this incredible gameplay and track design, these spectacular graphics (which look absolutely fucking INCREDIBLE in 3D), and yet... Nintendo gimped the most basic of customization options, namely, the ability to play a single race against the computer. Sigh.
