Awesome / Starbound

• Defeating The Ruin, finally getting vengeance on the destroyed Earth especially if you are a human. Even more karmic justice if you used the Protectorate's Broadsword to destroy it.
• The finale: The Ruin dies in a massive explosion, taking the player with it. You see your soul floating through space, and then the Cultivator gives the last of its remaining life force to bring you back to life... respawning you right into the middle of your group of grieving friends. Cue credits.
• Nuru and Lana warping in to aid your defense of the Baron's Keep.
  Koichi: Hello? It's me. I'm sorry, but — there are more cultists coming. Please don't worry, though; we're going to help! I'll just get in the way, but the others are coming down!
