Worst controller ever

[nintendo_fanboy]

I think it really depends on the controllers you grew up with if you feel comfortable with another one. At one hand, that is because we just prefer what we are used to, other things always mean we have to learn something more. Also, and probably a lot will not agree with me on this, I think Nintendo is always a step ahead of the concurrence in terms of controllers.

If Nintendo has done something right in their past, its the controllers. That is because Miyamoto's basic concern about a game is always: What can I do with my character, how can he move? If that is the main question for the developers, it is clear that a lot of emphasis is based on the controller.

So, Nintendo knew in the NES days that a d-pad is more useful than a joystick for 2D games.
A generation later, they knew that more buttons are needed and that a controller should fit your hand.
When they went 3D with the N64, they created a controller that put the Joystick in the main position (If you hold the controller correct, that is), while Sony put it to a secondary position and has still not changed that.
With the Gamecube, Nintendo understood that the d-pad has lost its importance and put it in a secondary position, making the controller a lot more accesible for new gamers compared to the N64's. Also, shaping the buttons differently may seem odd to people that are not used to it, but it is a great idea imo. Different to the PS, Xbox or also SNES controllers where you always had to check which button does what in a new game, you just new it with the Cube.
Now, Nintendo has changed controllers again with the Wiimote and the DS touchscreen, while Sony still sticks to their old controller after nobody liked the boomerang and Microsoft has at least adapted a lot of the things Nintendo showed them with the Cube.

If you look at the past of Controllers, you see that Nintendo was always the first to improve, the other only copied the new features Nintendo brought up. That is why people that are used to play Nintendo consoles sometimes have problems to use other controllers I think.
