Go mario kart
It is amazing. The basic thing is that mario wants to race and he brought more friends. This new game is good it has few of the modes like Single player, Multiplayer, Online play, and MK channel. The single player is about the same as ever. Theres Grand prix, Time trail, battle, and VS. Grand prix is where you go course to course and win 1, 2, or 3 place. Unlock more things and yadayadayada. Time trial is where you just take some practice and beat your ghosts and others. (nothing diffrent) Battle is a little different. The balloon and coin thing is there.But they got complicated from the DS thing. the balloon thing is run over and over. (you live again and again) until the thing is over. (there is no regaining balloons back.) The vs. thing is like solo mode and team mode. (team mode better!)
Multiplayer is the same as single (except with more people)
Online play is more better. You go worldwide, regional, and with friends. (worldwide WAAAAY better) also theres a race option or a battle option. (go with race)
And the MK channel is good. there are tournaments, rankings, and ghost trials. You can always check your rankings and see who your ahead or behind. Take your chances and try tournaments and try to win.
