Wtf endings:
Silent Hill 2 UFO and Japanese Dog ending
Day of the Tentacle
Twisted Metal: Black all the character endings

Bad endings:
Any Resident Evil game
Metal Gear Solid 2
Metal Gear Solid 3: Snake Eater (Mostly everything up until the cemetery part was corny and/or over-explained like 90 percent of the game. Seriously, who wrote the script to this game? Iceglow?
Indigo Prophecy Best Ending (The game went from great to The Matrix Revolutions for no reason.)

Great endings:
Silent Hill Mary and Maria ending
Red Dead Redemption
Final Fantasy VII
Heavy Rain (I don't know whichever ending makes the most sense. I didn't see them all.)


I don't even know how bad FFXII and FFXIII's endings are because I never bothered to finish them. It's an inevitable waste of time.
