Factorio

[Wraith]

I managed to play too many hours since an impulse buy on it's release on Friday when I should have been working instead of building pretend factories on an alien world. Very recommended.

It's an isometric game where you build factories and manage supply lines, and occasionally get attacked by aliens. The world is procedurally generated and infinite. It also runs way better when there are hundreds of factories and thousands of supply lines than it has any right to - I've yet to build anything sprawling enough to cause any perceptible slow-down.

It's also currently the highest rated game on Steam, ever. That probably won't last though.
