I don't really know what you're talking about, because I always feel all warm and squishy inside whenever I finish a game. It's like, "Wow, that was pretty good!" And it's especially nice if you unlock more features or a NewGame+ or something.
Of all places, I'd think an RPG Maker community forum was the last place I'd see a topic like this. We, of all people, understand that a game we adore does not have to end... we can create a sequel!!
