A quote from Japanese Gamer Cheesemeister that reads: ‘Mario games teach us that even if something is essentially the same, psychologically it can be completely different. This example is very easy to understand.‘ It shows two versions of a screen from the original Mario Brothers game with Mario moving up a series of steps made of block towers. In the first, the towers have holes between them but are built from ground to top. In the second, the entire ground is removed and only the top blocks of steps remain, with lots of empty space beneath them.
