Xbox Live Marketplace - Tetris Splash, kids game demos

This week, Xbox Live Marketplace is heavy on the Arcade add-ons and kids game demos:

• Tetris Splash ($10) and various bundles and themes totalling $15 (so it's a stealth $25 title if you want all of the launch-day content)
• Carcassonne King & Baron Expansion Pack ($3.75) adds seven new tiles including a king and a robber
• Soltrio Solitaire Game Pack 9 ($1.88) with 10 new games including Pyramid, Fourteen Out and Block Ten (fyi- if you've bought them all, you've paid about $27 to date but with more than 100 game types to show for it!)
• Demos: Bee Movie Game, Bladestorm (1.9GB!), Looney Tunes: ACME Arsenal and Thrillville: Off the Rails
• Game Videos: 3D Ultra Minigolf Adventures Lost Island Expansion, Fatal Inertia, Looney Tunes: ACME Arsenal, Madden NFL 08 and Spider-Man: Friend or Foe
• Themes: Crash Of The Titans, Fatal Inertia and Family Guy ($1.88 each)
• Pictures: Crash Of The Titans, Two Worlds, Family Guy and Zoo Crew ($1 each)

If this week is any indication, Microsoft and its partners seem to be standardizing on $1 for picture packs...
