My wife sent me a link to this game after a conversation I started when we were planning out landscaping for our yard (I wanted a defensive perimeter capable of holding back the hordes of the zombiepocalypse).  I though about buying this game after playing the free trial, but it has mucho "lost time" potential ("It can’t be 7am… I haven’t gone to bed yet.").  Not always the best thing for a writer (but the hour I played of it was fun).
