Worth buying for the free controller, but mildly entertaining for up to an hour, slightly boosted by 2-player.
The game consists of 9 minigames, but u only start with one. You unlock the next one when you finish the previous one regardless of your score. This is a good thing because the games would become tedious after more than one play. The first game is shooting (balloons,mostly). This teaches the obvious technique of pointing the wi remote. Later on it moves on to more advance techniques such as twisting it, or holding it sideways. Whereas you could learn these from real games where you need to do this, wii play offers a more friendly way to do it.
You are not buying a game which will eat away hours of your life here. However,credit where its due to something that will teach you the basics without boring you. If you want another wii remote, buy this. If you dont, this shouldnt cros your mind....
