Got a nice juicy announcement today from Valve about a stack of Ubisoft games coming to Steam:

Valve and Ubisoft, one of the world's largest video game publishers, today announced an agreement to bring more than 40 Ubisoft games, including Assassin's Creed(tm), to customers in Canada and the United States via Steam, Valve's leading platform for the distribution and management of PC games with more than 15 million accounts worldwide.

Assassin's Creed is now available for pre-purchase via Steam. In addition, Ubisoft is bringing many of its award-winning brands to Steam, including games from the Tom Clancy series, the Heroes of Might & Magic® series, the IL-2 Sturmovik collection, Far Cry®, and much more.

Unfortunately at this stage Australians aren't on the invitation to this particular party; Ubisoft Australia have let us know it is currently only for US and Canada residents.
