I had been searching for this game for months with no luck. Finally found it at Gamestop with no original case or instructions for 18 bucks. After making sure I could return the game for a refund, I bought it, took it home and got my 1k within minutes. It seriously took me longer to use the bathroom afterwards then it did to complete this game. I feel like a total cheat, but hey, achievement points are achievement points and they all count!
Funny thing, when I returned the game 10 minutes later, the guy who sold it to me asked me if I didn't like the game! He didn't know that Avatar was the one with the easy gamerscore. He knew of the game, just not which one.
