Tech demo coming out sometime this week.
It's a game that's a little like Spore in that you have a choice between a bunch of different alien features to start with (currently only showing human).
You can guide one or more civilizations to the space era and beyond like Civ 5.
And it's got the block format and building freedom of minecraft! Plus blueprints so you can save your designs or have them repaired by ai.
Looks pretty great but not enough support at the moment.
