There’s a great IGN article on their top 10 worst game controllers. Its all very good but I think they missed one out that you just cant omit from a chart like this.
My most uncomfortable controller. Unlike today’s controllers, moulded to the hand, SEGA decided round wasn’t cool, and sharpened the corners of the Master System game pad to fine points. I distinctly remember breaking the skin with this as a young boy, trying to beat Alex Kidd in Miracle World.
This would be my #1 in a top 10 of worst gaming controllers closely followed by the Spider-Man Plug’n’Play from TFA.
