Games with characters you miss most after completion.

It's a bitter sweet feeling afterward, but I love it when a game has characters where, after the game is over, I miss seeing a part of their lives. Be it due to the characters themselves or the interaction they have with one another, exiting their world feels more like a loss than when normally putting a story away.

Are there any games where you experienced similar? While it can be a bitter sweet feeling, I know that it is a sign that I really enjoyed what I was playing and love to find these experiences.
