Best and worst game endings

[Tiger]

Off the top of my head here are two from each category. They're not the best, or worst probably, since I might be forgetting some:

Good: Bioshock Infinite
Bad: Dishonored

The low chaos ending in Dishonored was so weird. I went into the room all stealthy, walking past the guys, and opening the door. Later I watched a video on it where the player just walked straight in, and the guys at the table just greeted him and gave him the key.
