From Austalia, a curious online action to raise money for charity. The tag line it's "You play, we pay" and it's basically just another smart way to promote the Xbox 360 game Halo 3, this time with an ethical marketing approach. By saying this I don't want to sound negative, it's a charity action, so I appreciate it by default.
The advergame consists of a golf challenge, the closer to the hole you shoot the ball, the higher the donation Microsoft will do to the charity organization you decided to play for. Looking at the numbers of plays registered on the site, the initiative seems to be pretty successful.
Congrats to Amnesia for the idea.
