That’s exactly how it works.
Left and Right are always relative positions, not absolute one. And they are relative not only to each other, but to the polics of the country as a whole.
Mount Everest’s high IS absolute, so it’s not a valid comparison.
Left and Right are, like what they are named for, merely directions. They mean nothing without a point to compare them too.
Right is typical the traditional position, orginally with the king, and left is the reform/change position.
Which is definitely true of right and left in the US.
Under Falling Skies is great, but it’s really more like the old Space Invaders game or even Missile Command and has nothing to do with Xcom other than involving an alien invasion.
It’s a one player worker placement game essentially.
