I agree. The point-and-click aspect of the Wii remote would be perfect for Civ, I don't understand what they were thinking when they cancelled the Wii version. I believe most PC users use a combination of mouse and keyboard actions and the Wii could offer the same functionality basically, especially now that there is an official Wii keyboard.
I remember playing Civ on the SNES, it was a pain to play with the D-pad but was a little easier to play using the mouse. I think the Wii Remote would improve the user friendlyness of console Civ and make it easier to play, so I hope they make a Civ for Wii some day (not necessarily CivRev)
