Were you on the fence on getting Civilization: Beyond Earth? Firaxis have just put up a demo for you to try out on Steam.

Of course, the full game is now available too, but if you wanted to give it a try before buying, Firaxis has your back. The demo is 5 GB and is turn-limited. You may not be able to play that much, but at least you can take your time making decisions if you want to.
You can download the demo here.
