It's Tuesday, which means: brand new Xbox Live Games on Demand to satisfy your very demanding gaming desires. There are two new titles this week. First up, we have Lara Croft's 2006 return to form, Tomb Raider: Legend. Next is Naruto: Rise of a Ninja, which is ... well, it's a Naruto game. Both titles run $29.99 in North America but, as usual, pricing and availability will vary by region.
