Launching on January 15, for $9.99 per month the 'OnLive PlayPack' subscription will let you play titles from a "growing library" of "recent, classic and indie titles" as much as you please. Over forty titles will be available at launch, OnLive says, but you'll have to judge for yourself whether the dozen confirmed so far are indicative of a service you'd happily pay $10 for each month. They are:

• Defense Grid Gold
• F.E.A.R. 2: Project Origin
• King's Bounty: Armored Princess
• Ninja Blade
• Prince of Persia
• Puzzle Chronicles
• Saw
• Tom Clancy's H.A.W.X.
• Tomb Raider: Underworld
• Unreal Tournament III: Titan Pack
• Wheelman
• World of Goo

OnLive has shaken up its business model a fair bit since launching in June, when it was planned that users would both pay a $5 monthly subscription for the service and buy a 'PlayPass'--essentially a full-price digital version--for each individual game. Plans for the subscription were cancelled in October, before anyone had actually been charged as the first year was free.

OnLive also launched a $99 set-top box called the MicroConsole, which was briefly offered free to existing OnLive members who'd bought two or more PlayPasses.
