Tear Jerker: Castlevania: Lords of Shadow 2
Dracula's depressing Motive Rant to Marie about why he has such hatred for God, forsaking his former identity as Gabriel to her face. Through it all, Dracula's voice is cracking the whole time, before finally breaking down.
This bit in particular:
Marie: I have been sent back to help you.
Dracula: You cannot help me! You're not here! You're not real!
The camera shows Dracula's face as he says this and you can see the tears threatening to spill forth.
Poor Toy Maker, the first time in what could potentially be centuries when he's completely himself again, it's immediately followed by the memories of what he did while in Bernhard's/Dracula's service coming back to him. Given that the real him seems like he's as kind as a saint, seeing him break down and cry uncontrollably may make you want to give him a hug.
Victor Belmont, Dracula and Alucard's last mortal descendant; sacrificing himself to draw out Nergal and make it easy for Dracula to track him down and kill him. In the short time we are dealing with Victor, we get a sense of there being a big history to him as a character, and a lot of loss and sorrow, and to watch him die heroically and announcing to Dracula that "you are now the last Belmont" is a heavy punch to the gut.
