Live you don't have it already
What good will MSP do you if you don't have Xbox Live? The answer to this question is SO obvious.
Do u play more games online or do you like to DL arcade games more?? Answer that and you will have answered your own Q!! I'd take the points and DL some arcades or get some DLC for another game
