Best and Worst Game Ending?

We played many games. some has good graphics, some has good gameplay, some has good storyline. but do you remember any game that has best and worst ending in your views? what do you think. what is your most satisfying and worst game ending? mine.. Best = Mass effect 3 (for some its a shock but i'm serious :D) Worst= Dead Rising 2

Why is this in the PC forums?
