What a GREAT Game! Some of the tasks are quite hard and this probably would be better for those over 10 and under 70.
Play the STORY line at the first screen choice and make sure you set aside up to an hour to complete each segment. You HAVE to complete (i.e. win) at least three tasks in the Arena and then complete one more task before getting thrown back in your prison cell. If you don't do these, you can't get back to your cell and you lose all what you have achieved for that days tasks. Your story position is automatically saved when you land back in your cell (this is not obvious) and you exit the game by power off or return to the Wii main menu.
Thoroughly recommended and I can't wait to have some friends over to play!
