Can I use a game controller to play Diablo 3?

Can I use a game controller with Diablo 3? Since there are not that many keys that are actually used, can you map a controller to play? Or would this require some type of mod?

Solution 1:

Not within the game, no you cannot use a game controller to play. Diablo 3 on PC is intended to be played with Mouse & Keyboard.

Using an external program / mod to add this capability not a good idea, as it is most certainly against the EULA. Using external things to change the game experience is a potentially bannable offense.

Edit many moons later: section 2-2 of the EULA (http://us.blizzard.com/en-us/company/legal/d3_eula.html) is pretty all-encompassing about what you agreed you will not do:

Use cheats, automation software (bots), hacks, or any other unauthorized third-party software designed to modify the Game experience, including without limitation, mods that violate the terms of this License Agreement or the Terms of Use;

I would personally categorize a system to use a GamePad without going through the game itself to be something that is "designed to modify the Game experience."

Diablo 3 is now playable on consoles, which obviously use GamePads to great effect, but the game mechanics are subtly different to compensate (for example, on consoles there's a dedicated dodge mechanic). I'm not sure why they never got around to enabling GamePads on the PC version, though.
