Two Tom Clancy titles are added to the Xbox 360 Games on Demand service, unless you don't live in the UK or Europe (excluding Germany), in which case there's just the one.
The first Tom Clancy's Ghost Recon Advanced Warfighter game is now available everywhere but Australia, New Zeeland, and Korea for the low price of $29.99, which is only $22 more than a used copy at GameStop. Slightly less available is Tom Clancy's Splinter Cell: Double Agent.
Availability: Not available in Australia, Germany, Japan, Korea, New Zealand or North America
As the commentors at Major Nelson's blog are pointing out, there's a time when you really should just tell the nice people where the game will be available, to save everyone a little time and trouble. Congratulations, most of Europe and the United Kingdom!
