5. Starlancer - Destroying the Coalition Second Fleet
A criminally underrated entry in the space sim genre, Starlancer dropped the player into the middle of a multi-planet war between the forces of the Alliance (space NATO) and the Coalition (interstellar Soviets). When the game begins, the Alliance is on the ropes after a devastating sneak attack. Much of the story campaign, in turn, follows the player's efforts to turn the tide and whittle down the Coalition's overwhelming strength.
This comes to a head in Mission 21 when you and your squadron are tasked with flying stolen attack bombers into the middle of the Coalition's Second Fleet with the intent of blasting it back to interstellar rubble. What stuck out most to me was the deep sense of satisfaction it delivers. Much of your time in the mission's opening moments is spent tensely moving through the enemy fleet, trying your best to blend in and look inconspicuous. You go through minutes of this and, honestly, it kind of sucks. That being the case, the feeling of satisfaction you get from finally being able to pull the trigger on your torpedoes at point blank is just immense and worth every second.
