South America is a great choice because down there, there are issues that aren't simply present in the United States, Canada, or Western Europe. It's a chance to see a whole new system of politics that aren't dominated by the normal situation of demographics in the US, or what Hash had said:
Yes, South America provides an interesting challenge in that it's not a place which has the capacity to support a wet-dream of a welfare state off the bat, unlike US/Canada or Western Europe.
And we've already done these US games (with a lot of policies that look like Europe), and when you try to do that in a game that has failed many times before (trying to also be American), it's going to be a quick transition to Atlasia, where TNF somehow nationalizes energy across the continent and where the right wing is in a constant state of collapse.
Even with the 80's European Union game, we'd have three situations of what exactly would happen:
-the USSR collapses (as it does in 1991)
-the USSR grows stronger and starts to spread its influence over Europe
-everything stays exactly the same as it did in 1983 or w/e
I, for one, would like to try something new instead of a something that's 10 years old, or where we can expect the outcome. New = better than eventually turning into Atlasia 2.0.
