I would join a resistance, then one of two things will happen.
1.) I'll die fighting and be declared a hero.
or
2.) I'll kill the leaders of the invading army, be a living hero for awhile, have a wife, two kids, and a job. Then get fired from my job after 30 years of faithful service, find out that my wife had an affair with 6 other men, and had 3 children with each of them, then find out my son is a junkie and my daughter is a law student. My daughter gets my son sent to prison for drug possession then leaves after my wife and I divorce and she takes 99% of what I have. I then get a job at wall-mart as a greeter, before finally dying of old age trying to find out where my nostalgia photos are.
I think option 2 is a bit of a stretch, but it's possible.
