I just completed my order this morning. I reserved it about a minute before the official opening of reservations. Hopefully you get your email soon! Delivery says 3-5 business days.

It looks to be actually called "Microcivilization"

Does the Steam controller wake the Machine?

The right trackpad will show a mouse on the screen and clicking the pad will function as selecting what you are hovering over. Left trackpad can scroll. This is with the puck plugged into the shield. I can do some more testing in a few hours.

After connecting the controller to the Shield via Bluetooth, I am able to navigate the menus with the D-pad. For some reason I wasn't able to use the controller to use the on-screen keyboard when searching, either using the D-pad or the right touchpad as a mouse. Maybe I am missing something there. I installed the Steam Link app and steam recognizes it as the Steam controller with all the functionality you would expect.
