Mario was first introduced in 1981 in the Donkey Kong game that was available in the arcade. At that point he was known as “Jumpman,” however he looked exactly the same as the Mario we have all come to know in the Mario Bros. franchise.
The Mario game that brought the character to its popularity was the first “Super Mario Bros” game that was introduced for the Super Nintendo and is now known as the best selling game of all time. It was known to be the best developed side scroller of its time which opened its doors for the developers to enhance its development for future Mario games.
Mario’s development into the 3D world helped excel its brand to the Nintendo 64, which today is still known as the best 3D platform game that has ever been created. There have been many other clones of this game but none have ever reached the level of success as Super Mario 64.
In competition with Nintendo, Sega wanted its hands on the Mario Brothers fame. They created Sonic the Hedgehog who would help market the Sega Genesis to compete against Mario and the Super Nintendo system. Sonic was built as a character that was a lot “hipper” than Mario and had a little bit of attitude.
Sonic’s first game introduction did not really get much success until it hit the 16 bit console system with its side kick Tails. Tails was a character that was made to be played as the second player in the Sonic the Hedgehog game franchise.
The 3D development of the Sonic games did not gain as much success as the Mario games did, that is until it was released on the Sega Dreamcast. This is where we saw a 3D Sonic game titled “Sonic Adventure” which was really worth playing.
