These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Tear Jerker: The ending of RayForce. Our un-named heroine dies when the resulting explosion hit her RVA-818-X-LAY fighter, destroying it along with Earth. The final seconds of the credits pans to what remains of the wrecked fighter, and then we see the dashboard displaying Mission Complete just before the ship's power finally dies.
RayStorm as well. Consider that you just committed genocide of an entire planet in order to stop a rebellion. The 13-ship mode makes it even sadder, as Earth itself got destroyed as well, and the player's ship was left to drift in space, never to be found again.
