10 Video Games That Made You PAY EXTRA For The Ending
9. Fallout 3
Fallout 3 is a classic of how to do a story right - except for the ending, really. After waging a massive assault on the Jefferson Memorial you, the player, are given three major options. You can basically do nothing and let everyone die, kill yourself to fix the water cycle, or kill your colleague to fix the water cycle. The end! The game then lets you know how your actions affected the world around you, whether you killed yourself or your partner.
But then the Broken Steel DLC came out, retconning that whole ending by letting you also send one of your other colleagues, who is immune to radiation, into the water purification controls. This allows you to continue with your quest without killing yourself or Sarah, your poor innocent radiation-affected cohort. Broken Steel fixes one of the biggest plot holes in Fallout 3, because why would you sacrifice yourself or someone else if you had someone who could safely do it for you, right? Though the whole game calls you a coward for doing it.
Of course it also creates a plot hole in that - if you made the sacrifice you're just magically okay a week later.
