Result visibility has been fixed -- that option was apparently reset when I was fine-tuning the poll expiration time. Sorry, poll watching junkies, but I think this kind of blind campaigning is more productive and more about the games themselves than "vote for this, it's almost tied".
I had some tough choices when making this poll, as there were many good nominations, and the VC selection of NES games is impressive. As DrewMG noted, Zelda II just seemed like a more interesting choice than the original one, which is universally loved. I originally had SMB: Lost Levels, but while it may be interesting, it would also be another brutal game following SGnG. So I replaced Lost Levels with Mega Man 3; I agree it is almost too beloved for this feature, but it was nominated multiple times and has some interesting elements (sliding, Proto Man, stage remixes, comparisons to MM2). Wrecking Crew is one of the most obscure first-party NES games, so it seemed like a good choice -- I have no idea whether the game is fun, but this would be a good chance to find out. StarTropics is a unique game that should have more exposure, and it's a personal favorite of mine. River City Ransom is a cult classic with some very interesting hybrid gameplay, as well as a full cooperative mode.
Just be glad I didn't nominate Milon's Secret Castle. (Maybe next time!)
