Is sonic rush adventure a really worth getting game?? i know it rocks but it was

released in what, 2005?? i never did hear about the game. now i am puzzled, to get

 sonic rush or sonic rush adventure. and i am living in malaysia and i dont know if

they are selling it or have any in stock. i will just try my luck when i go to the city.

now, sonic rush or sonic rush adventure. or should i just get pokemon diamond?
