Answer: Super Nintendo Entertainment System
Released to North American audiences in 1991, the Super Nintendo Entertainment System (SNES) had a different exterior than the Super Famicom (the Japanese version of the SNES). The differences were more than simply cosmetic, however.
Specifically, the SNES case was designed with raised buttons, trimmed surfaces, and a curved cartridge bay while the Super Famicom was, by comparison, nearly flat. At first glance, it may just appear to be an aesthetic choice, but it was driven by careful market testing and feedback from Nintendo repair centers.
The U.S. The first generation Nintendo console, the Nintendo Entertainment System, was a very boxy console with a flat top. So flat that players would often place drinks on top of it and, albeit less frequently, would play those same drinks. When it came time to launch a new North American console, the design was tweaked, to discourage players from placing things on top of the unit and thereby reducing the number of consoles sent in for repairs.
