I voted for the 1 vote = 1 game option. The only real merit to 12 hour system is having an accurate, representative result, but even that doesn't seem necessary for most matches, seeing as scores are often one-sided. I don't see how using a tennis scoring format entails that we're changing the whole system to be like a tennis match. A tally count, although easier, will make things far more dull, in that there won't be any amusing commentaries generated from it, etc.
If a match is so one-sided to the point that the poster gets 18 consecutive votes, then it's safe to say that the format won't make any difference.
The tournament will be very boring if the #1 format gets chosen. Instead of thrilling five-setters, we'll get handball-like scores.
