Scorched earth.
The rest of those games falter, because every single one has been replicated with more modern graphics, higher visual quality, and better overall polish. Whether homage, or thievery, this makes the originals difficult to go back to. My nostalgia is often blunted by the, by today's standards, relatively harsh aging these games undergo.
Scorched earth may have worms competing with it, but it really can't be replicated. Otherwise, I would have to say all of these games have nostalgic rings, which are hollow if you actually listen to them.
