It would be an unanswerable question for two best thing from them, brawl is a fighting game that I know and MKW is a racing game, brawl shows that you could play characters of any game series they come from and put one of them to their most favorite character that they like to play with other fighters from any game series that they could met, and MKW is actually the game of only Super Mario Bros. Series that is a Wi-Fi game to race with only those characters that including your mii in the race, also it have a wii wheel to race with for a new control set and unlock a new channel for your wii menu to get records of MKW you did and even race with others of more than 4 characters on Wi-Fi, that was how they look good on Wi-Fi.
