I have checked with the manual how to access the multiplayer game mode.
However, the window shown on page 20 of the manual appears different in the game when I try to access it.
Instead of being able to click on a box reading 2player/3player or 4player, the boxes appear blank. I had first presumed that maybe the second wii controller wasn't correctly on, but everything seemed to be normal, except that maybe the game won't recognise another controller.
I have wondered if I need to complete the game in single player mode before being able to access multiplayer options.
I wonder if it is a fault with this particular game and it needs exchanging for another.
