I know Wikipedia isn't the ultimate arbiter of truth, but this is how it's article on Fascism begins, and I think it would be fairly common for people to consider fascism a form of authoritarianism:
Fascism is a far-right, authoritarian, ultranationalist political ideology and movement,[1][2][3] characterized by a dictatorial leader, centralized autocracy, militarism, forcible suppression of opposition, belief in a natural social hierarchy, subordination of individual interests for the perceived good of the nation and race, and strong regimentation of society and the economy.
FWIW I'm not meaning to attack democracy here, I find it to be far preferable to the other systems we have at our disposal. But it is a tool that can be used for good or bad.
I enjoyed the original playthrough despite all it's warts, been waiting for it to get to "2.0" before picking it up again. Will have to wait to hear reviews on it, obviously, but everything sounds good so far.
