Xbox 360 Round-up - Demos, patches and more

If you haven't been to Xbox Live Marketplace lately, there are some new wares worth checking out:

• New single-player demos for Ghost Recon Advanced Warfighter and Kameo (free)
  
• Another add-on for The Elder Scrolls: Oblivion, the Wizard's Tower ($1.88) again favors mages though does provide a well-stocked garden for alchemy fans and a spectacular view
  
• Autoupdate for MLB 2K6 that apparently fixes problems for some users and causes them for others (free) as well as a trailer (free), picture packs ($1 each) and themes ($1.88 each)
  
• Trailers for Blazing Angels, Dead or Alive 4, FIFA World Cup 2006, Lost Planet, and Rockstar Table Tennis (free)
  
• More Nacho Libre promotional videos (free)

Also, Project Gotham Racing 3's Online Career leaderboards have been reset due to changes in the matchmaking system. The good news is that you should find better matchups after about six races...
