If by good you mean worth playing for, then yes. In the Mario and Sonic London 2012 Olympic Games, Beijing Olympic Games, and Winter Olympics for Wii, there is a wide variety of characters from both Super Mario and Sonic the Hedgehog, good and bad guys. You can select one character to play with against other players in Olympic events. Its definitely an awesome game.
good question I think in the first sonic and mario game,or youtube
No, Mario isn't on sonic the hedgehog game.
Yes
Mario and sonic at the olympic games
Of coarse not, Its not called super sonic galaxy 2. (that would be a good game)
There is no sonic game that is like mario party because Sega has created sonic games different from some mario games.
If you are talking about Sonic and Mario in a Smash Bros game the they are both in Super Smash Bros.Brawl.
Belive it or not, the first time Mario and Sonic appeared in the same Video game was Sega's Mario and Sonic at the Olympic Games made in 2007
Sonic Shuffle
Mario&sonic at the winter Olympics
sure first was Mario and sonic at the olympic games then Mario and sonic at the olympic winter games then its Mario and sonic at the London 2012 olympic games
Sonic the hedgehog is an awesome series, and its nothing like Mario
