I’ve played Ingressfor several months now. It is interesting to note that it happens to reflect the binary nature of American politics so clearly:
There are the Englightened, who are welcoming to change, and see it as a possibility. There are even undertones of migration with the alien entities clearly trying to gain a foothold in our reality. These values happen to coincide with the progressive side of the political spectrum.
Then there is the Resistance, who oppose the new entities as alien and basically suspicious. The Resistance sees any effect they might have on humans as at least potentially dangerous. This happens to coincide with the world view of the conservative side of American politics.
Is it intentional or just a result of the world view of the designers?
