There's a setting in the options panel that allows me to connect my Facebook and Twitter accounts with the game. I assume this will allow you to post about your achievements in-game. Is this correct? Does this unlock any other functionality that might be useful to gameplay?
It allows you to share short text blurbs about achievements, mission completions and some in-game events (e.g. elections) to Twitter and Facebook, and also post screenshots to Facebook.
(Note that we never auto-post; Facebook/twitter buttons appear on some dialogs, and you have to click them to post.)
Nothing, it will fail to connect every time.
