OnLive (for iPad)

The interface is effectively identical to the PC and MicroConsole versions of the OnLive software, with a grid-based menu system that lets you select, Mega Man-style, the My Games, Marketplace, Profile, Arena, Showcase, Last Played, Brag Clips, and Friends features.

You'll spend most of your time in My Games, which holds all of your game purchases and lets you select the games you want to play.

Some games, like L.A. Noire and Defense Grid Gold, have gotten complete control system redesigns to make them work with a touch screen.

Others, like Lego Batman, map controller buttons onto the screen like the virtual controller in most mobile games that require directional controls.
