I prefer to play with a Wii Remote myself.

It's pretty easy to set up if you have a bluetooth enabled. Unfortunately, I wouldn't know how to set it up for you people on Windows machines because I'm on a Linux machine myself. wminput is what I simply used in my GNOME Terminal. Accuracy is a bit of an issue with the IR sensor. I had a bit of trouble closing the menu that I previously opened with boost. I'm only wondering how this would perform in an actual depth of clockworks. Otherwise, the Wii Remote plays flawlessly within Spiral Knights. If you wish to get this working yourself, I can elaborate further for you.
I still think you guys are silly for choosing Xbox/PSX controllers though. :P
:o That's pretty cool.
Maybe SEGA might publish SK on the Wii since it's controls work so well with it... lol
