This game had the potential to be really great, but unfortunately, bad graphics and even worse controls make it a flop.
The aiming system is atrocious, you'll be glad that you can use the Wiimote to aim, and the Nunchuk to throw. It's a lifesaver, and it's challenging.
The graphics are typical Wii graphics, so nothing special on this front.
The character customisation is below average. Your darts player can only be right-handed, there is only 4 different darts flights, there aren't that many feaures to customise your character.

If you're a proper darts fan, give it a go, but don't set your hopes too high. The game is poorly made, but it's the only darts game on the Wii, so it will have to do for now.
