This is definately true. Many RPG games come to mind that do exactally this.

For the most part, no. A d-pad and an analog stick work in fundamentally different ways.

Let's take the playstation controller for example. The d-pad is actually an array of 4 buttons, one for each direction. Also keep in mind that no more then 2 directions can be pushed at any given moment due to the nature of the gamepad. You can't press up, down, and left at the same time, for example. You have a total of 8 possible combinations with a d-pad, 4 cardinals and 4 diagonals.

The hardware handles this as 4 boolean values. An analog stick on the other hand is a pair of 2 analog axis. The hardware handles this as 2 signed 1-byte values. A full range of motion should permit for 65536 distinct direction/intensity combinations.

Due to the "all or nothing" nature of d-pad hardware, mapping this input to an analog stick is, at best, exrteamly awkward, involving rather ugly workarounds involving timed or multiple presses that make most games totally unplayable.

You sure about this? There's generally a "deadzone" setting for analog controls, which defines how far from neutral the control can go before it starts signaling.
