I somehow missed this last year (thankfully, SUSD are moving all their content to Youtube so you can subscribe to their channel and get boardgaming gems new and old popping into your life every day).
Watch the Skies is a megagame inspired by the X-COM series. In the game, teams of players represent countries, and within teams each player holds some position within the government of that country (Prime Minister, Foreign Minister) giving each a specific role in the structure of the game and access to certain areas and decisions (for example, only Foreign Ministers can visit the UN). There are also players representing the aliens, the global press, and it’s pretty sandboxy!
I would love to get involved in something like this. Who fancies going to Westeros?
