Save your money for another game and continue bowling on Wii Sports.
AMF Bowling is dull and irritating, the graphics are not too bad but the whole experience is lacking. The choice of playable characters are acceptable if a little male orientated with scantily clothed female characters. If you don't like the Wii Sport "cartoony" look then these are a little more life like. But there is no option to play as your Mii and there is no atmosphere as the other lanes are devoid of any other players. Also the characters obscure the view when trying to aim, although you can zoom in to aim more accurately. The in game music soon starts to grate on your nerves.
There are a number of mini-games which I can't comment on as I couldn't bring myself to try them after playing a bowling match. Save you money this game is hopeless.
