I really can't recommend strongly enough that people avoid this game.
The format is basically thus: Three or four multiple-choice questions, you can see everyone's Wiimote cursors during answer selection, but the first one in gets more money, and then everyone has the chance to spin the wheel, which randomly adds or subtracts money, sometimes coming from another player, sometimes from the bank. Lather, rinse, repeat a couple times.
If all you care about is that it looks like a game show, then by all means spend the $10. If you want an actual entree with your appetizer, you're going to be disappointed.
