Xbox Live Marketplace - Forza 2 add-ons, reasonably priced

This week is another light one for Xbox Live Marketplace. Apart from the previously reported free BioShock and dashboard updates and those permanently discounted Xbox Live Arcade Hits (which took the place of the weekly Arcade release), here's what's new:

• Forza Motorsport 2 Road America Track Pack ($1.25) and December Car Pack ($5, or get the Renault Clio 197 free)
• Rock Band Black Sabbath Pack 1 ($5.50, or $2 per track) with cover versions of "N.I.B.," "Sweet Leaf" and "War Pigs"
• DDR Universe 2 Song Mega Pack ($10, or $1.25 per song)
• Demo: Culdcept Saga
• Game Videos: Grant Theft Auto IV and Switchball
• Pictures: Assassin's Creed ($1 each), Santa's Friends ($1.25) and Mrs. Claus & Friends ($1.25)

It's worth noting that Microsoft has implemented business rules making all free content exclusively for Gold members its first week of release. Now Silver members actually see a symbol showing that they can't have it yet...
