Super Mario Bros.

Shigeru Miyamoto had originally wanted to give Mario a dinosaur to ride on for the game, unfortunately the hardware limitations of the NES wouldn't allow for it. He was able to finally fulfill his wish in Super Mario World (1990), which ran on the far more powerful Super NES, and named the dinosaur Yoshi.

At the beginning of the first level of each world (except for the first one), it shows Mario standing in front of the castle, which he had just previously cleared in the previous world. However, at the beginning of World 5, the castle is only a mini fortress instead of a full-sized castle like it should be.

In 2010, Nintendo released a limited edition red variant of the Wii console as a part of celebrating the Super Mario series' 25th anniversary. As a bonus, this version of the system came pre-loaded with "25th Anniversary Super Mario Bros", a modified version of the original NES game. The only difference is the graphics for the item blocks, which now have the number "25" on them instead of questions marks.
