Gaming has come a long way in the last three decades in many respects, though I think controller design gets overlooked. Some of the older controllers were absolutely brutal to use for extended periods of time. The NES controller, for example, dug into my hands after a while. Those squared-off corners sucked. The N64 controller could be pretty bad for your thumb, too, if you needed to quickly whirl the joystick. Which of these old school beasts did you like the most? Mine is probably the PlayStation. It has a sleek design, it fits nicely into your hands, the buttons are laid out well, there's no confusion as to button location, and it's comfortable for long periods of time. It doesn't shock me at all that the controller's layout hasn't changed a whole lot between all four of Sony's major gaming consoles. It just works.
