I got this idea playing Ketsui: Death Label...
Basically, you fly a top-secret mission for the government that must never be revealed to the world.
This means you will either die in battle, or the government will kill you when the mission is completed to make sure the secret stays a secret.
The government will grant you one last wish before you die, provided that you complete the mission, and that wish can be ANYTHING you want... Just remember that you wont be alive to see a long-term plan!
So what would be your last wish?
