Mario Party 8 because look at all the mini games and different boards it have made it more enjoyable if it had wifi. Also,Mario Galaxy,I mean think about adding minigames and having timed races that was 4 player accessible for every star mission. Like P1 Mario P2 Luigi P3 Yoshi P4 Toad, I would have really liked wario in it (aside from the fact that he is my favorite) because he would have made a good comical, mischief maker. I say this because their all connected like Mario and Luigi:Superstar Saga had Popple. Bowser's Inside Story had Midbus. Mario RPG game had Croco. Paper Mario had Koopa Jr. Sorry for the ramblings, trying to make a point to having Wifi for MP8 and SMG. Lets face it games would make more money off this option. There is a connection between people and Wifi that makes things more enjoyable.
