OnLive boss Mike McGarvey has promised consumers "original, exclusive" games for the platform when it launches in June.
The firm announced at GDC this week that the platform would launch in the US on June 17 on PC and Mac for a monthly subscription of $14.95.
However, the company didn't announce when its MicroConsole - which allows its server-based titles to be played via a TV - will launch.
The platform has won support from Electronic Arts, Ubisoft, Take-Two Interactive, THQ and Warner Bros.
OnLive will offer up to 20 titles at launch include Assassin's Creed II, Prince of Persia: The Forgotten Sands and Metro 2033.
"While we can't comment on games currently in production, the OnLive SDK is being used by a host of developers, both big and small, and we expect original, exclusive gaming content to be a major component of the service going forward," OnLive COO McGarvey told MCV's weekly magazine.
McGarvey added that the company had no firm launch window for Europe currently planned.
