Games that made me depressed after they were over
There are a lot of games that aren't long enough, and a lot that might be too long. This list doesn't necessarily mean that the game should have been longer by any means, in most cases it would only hurt the game as a whole. Some games are just the right length.
But then there are games that after you beat them you're like: "man... I really wish this wouldn't have ended, I enjoyed it so much." And it puts you into a sad mood for about a week, until you finally move on to something else. That's what this is.
(Also this isn't a list of sad games, or games that make you tear up, I'm talking about games you are legitimately sad about the fact that theres no more of the game to play)
