Crisis Core or Metal Gear Solid 4 - Which had the sadder ending?

[SuperiorX99]

I got to say Crisis core. Although I love MGS4 to death, and the ending was amazing, Crisis core was heartwrenching. Zack dying impacts not just the game, but the characters. You can tell he struggled, the same with Solid Snake and most of the characters, however, Zack dying truly the most sad thing I have seen in a while.
