It’s another interesting week for Xbox LIVE Marketplace’s Games on Demand service, which gives Xbox 360 gamers the opportunity to download current generation titles for a nominal fee.

This week, Games on Demand sees the addition of the well-received Shaun White Snowboarding, as well as the action-packing real-time strategy game, Command & Conquer 3: Tiberium Wars. Here’s a snippet from Shaun White Snowboarding’s description:
