once upon a time mutant aliens take over the world and kill 90% of the human population. Now they're making a prequel set in the events of resistance 2, it makes you think whats the point if you know that all the people around you will be dead including you. Makes the whole fight pointless.
I think that's kind of the point, to experience the sense of helplessness in a one-sided war. I've not played Burning Skies, nor do I intend to, but I can respect that it's a spin-off exploring a different side of the Resistance universe.
