Tear Jerker / Eternal Daughter
The freeware game Eternal Daughter, though better known for its terrific gameplay and high difficulty level, rewards the player with two of these towards the end. First, when the heroine, Mia, finds out that the god of Nature, Eluriel, is her real father. Second, after defeating Baphomet, the final boss, she falls fatally ill, and dies, but her spirit is taken up to Heaven, where she becomes a demi-goddess, all to the accompaniment of music to be resurrected to. Wow.
