A great price for this cooperative people-vs-germs game (even if it was $19 for Black Friday). There are many, many sequels and expansions, but the original is still a great entry point. Also get the same price at Walmart. 

If you missed out on Black Friday deals for the original Catan, check out this offshoot of the popular exploration, settlement and trade game. Like chocolate and peanut butter (at least according to the old TV commercials), GoT and Catan seem like they'd go together well.
