I got this game last weekend, and I have done little else since. My RSS feed has been neglected. Emails are piling up. The grass is past a much needed mowing. This game is seriously addicting. There is a very good sense of satisfaction from improving the output of one component or another, or getting train routing up and running, or better optimizing the logistical robot network. It also has some pretty in-depth mod support, of which there are many. The crazy thing is, this is still beta. There are several things on the roadmap including multiplayer. This has been a seriously good purchase that I would recommend to anyone.
