Most of the new games that have arrived on the Gaikai cloud gaming network are from a new source, namely Ubisoft. The new Ubisoft games on Gaikai are Anno 2070, The Adventures of Tintin: The Game, CSI: Crime Scene Investigation: Fatal Conspiracy, Assassin's Creed: Brotherhood and From Dust. The only game from the aforementioned available on OnLive is Assassin's Creed: Brotherhood. The other games, with the exception of Anno 2070 and From Dust, are meh titles that OnLive gamers won't miss very much.
Yes, Gaikai got From Dust, the game that OnLive advertised as a flagship launch title for OnLive mobile touch controls.
From Dust is still nowhere to be found on OnLive with or without touch controls. This is another blow that Gaikai dealt to OnLive, after The Witcher II first came to Gaikai and the OnLive version is still nowhere to be found.
2K Games is another new partner of Gaikai that brought The Darkness II with them. I'm sure OnLive would also love to release The Darkness II on their cloud gaming service.
The other new games on Gaikai are Dead Rising 2: Off the Record from publisher Capcom, Mount & Blade from Paradox Interactive, Arcania: Gothic 4 from JoWooD Entertainment and Orcs Must Die! from Robot Entertainment. Orcs Must Die! is the only one from those games available on OnLive.
