Utterly subjective list of games that left me with the emptiness
once I have finished them

There are few games that left me with a sudden emptiness once I have finished them. The emptiness came from the simple fact that the game itself was over and there was nothing more to achieve and develop.

The list is in a completely random order (most probably chronologic one, but no 100% guarantee).

Edit: It turns out my intuition was spot-on :)
