There's only one week left of Nintendo WiFi Connection, so if you haven't downloaded puzzles on the first four Professor Layton games, or shared creations on Mario vs. Donkey Kong, you better get on it! It's also the perfect time to play some Mario Kart Wii online, since Mario Kart 8 comes out in 18 days! Or play Super Smash Bros. online since the new 3DS version comes out soon! Or play Tetris DS! Or Pokemon games! Or MarioKart DS! Or whatever! Go do it!
