Thought I'd create a thread for those of us who like our tablet gaming to be sans additional peripherals
These are the options I've found thus far, I'll keep this post up to date as I find others or alternatives are suggested.

Available on Steam, supports potentially any game with a number of pre-built controllers present via Steam Workshop integration.
In general once you figure out how to make it work it's quite good, but it has some limitations. Specifically I've yet to make mouse look work well with just the touch screen, however using a mouse and an overlay in lieu of a keyboard works well for me in games like Oblivion and Modern Warfare 2.

Not one I've tested yet, seems quite polished from the website however only supports a very limited number of games without option to create other configurations. They sell a number of prebuilt controller profiles for games, but each game profile is a separate purchase which makes it slightly less appealing than other options.
It does take some time to get used to it and configure everything. I can confirm it does work, by results really do vary between games. The biggest issue I have is with emulating the mouse movement / mouse look using either a virtual joystick control or a global gesture. Still not figured out how to get that working smoothly.
