Expedition 33, the gem, made me think of this. There is no specific order, but my top 10 is as followed.
- 
OG Aerith - the unexpectedness of it. Her kind heart and wonderful personality. And to be taken away like that. 
- 
Noctis - He grew on me during my 167 hours with FFXV. Him and his bros were inseperable. That final campfire hurt. 
- 
Lee Everett - Everything he did for Clem and then he goes out like that. He was a boss. 
- 
Dom - Marcus’s bro. Seeing how pitiful he became in GoW 3. Death was a relief. 
- 
Ghost and Roach - WTF Shepard… 
- 
Gustave - I fell in love with his relatability. He was just this normal dude doing an inhuman task and he did it well. Made great bonds. Badass arm. And then… gone. 
- 
Zack Fair - The opposite of emo Cloud. This dude loved life and he sacrificed his to save his buddy. 
- 
Galuf - Went out like a Chad to Exdeath. 
- 
The Virmire sacrifice - regardless of whether it was Ashley or Kaiden, the fact that they were gone for good because of your choice hurt like hell. 
- 
Crono - Talk about a plot twist.

So true. I still remember, that I was like “yeah, let’s go for a last mission today and go to sleep.”
It, in fact, was a final mission and I was playing as high honor Athur Morgan…
So emotionally this was the most unexpected and best death of the protagonist ever!
