To Jonny: The more I thought about it, the more it's apparent that there isn't any one size fits all solution to polls. If you could trust people not to be jerks on the Internet (cue "The Impossible Dream" music), you wouldn't have to mess with IP tracking or cookies (though both can be easily gotten around if someone wanted to, I assume with Google the important thing is the account itself. Once that is voted with, IP addresses don't matter as it can't be voted with again).
I suppose one could truly get around those restrictions by making multiple accounts and voting in that manner (though why would anyone be that lame). In that extreme case I would say that would be a point in favor of the NWR Forums. After all, if suddenly 60 accounts were registered on the forums in a week and they all voted for Choaniki in RetroActive, that kind of suspicious activity would be easy to detect.
But at some point you just have to use whatever method you deem the most necessary, since people intent on mucking up the vote will do so if they are sufficiently lacking in life. And besides, this is voting for what videogame to play, not the Presidency, so it's not worth it to plan for every possible contingency anyway.
To Jon: There are enough neglected Nintendo franchises to choose from, it's easy to be confused. Just imagine if you were a huge Capcom or Namco fan. Throw a dart at the board and you'd land on a neglected franchise with those two.
Though to echo Gui's point, while there may be neglected IP, Nintendo will sometimes surprise you by what they choose to bring back. Talking about F-Zero, I agree with what Gui said in a past episode discussing Nintendo waiting until a new control or new way presents itself before they make another. Just make the game! Just update the graphics, use your creativity for the tracks, characters and get on with it. I could see being concerned with freshness if you were pumping the games out, but it's been over 10 years. Just making a F-Zero game at this point is the refreshing bit, no matter how it controls!
No one in power at NDCube is that concerned about freshness in the Mario Party series. Why are some series held to such high standards and others not? If it's a question of finances, then just say that to the fans and cut bait. Don't talk about waiting for control schemes that will suddenly make the game worthwhile.
I can understand not wanting to repeat yourself (though this is Nintendo we're talking about), but when a decade passes between releases, if there is fan demand for it, you just have to give it your best creative shot and not wait for control schemes to bail you out. We already see how that works out with Rainbow Curse, not being able to look at the pretty graphics on the TV while you're playing. New doesn't always mean better and it's best to stay with tried and true than to shoehorn in controls just for the hell of it, which Nintendo has guilty of more than once.
