If you haven't scooped up the series yet, then there is no better time to do it than today. As part of their Countdown to 2013 deal, each episode is only 200 points (regularly 400 each), and the first episode is free to download, so if you haven't given it a shot, download the demo and give this wonderful game a few minutes of your time. A truly great game at a really good price.
Seriously, go do it.
