They’re holding a Visual Novel Contest at GameFaqs the “Anime and Manga – Other Titles” section (Eab1990’s favourite). Not a very large number of voters just because VNs are not that popular and also because you need to have played both games in that round in order to vote.
The diagram is a bit confusing but basically if it says 17 / 14 / 30 / 4 / 10, I’m pretty sure only the first two numbers count as votes.
So in the very first round (1)Fate/Stay Night VERSUS (8)Kamidori Alchemy Meister, 17 votes went to F/SN & 14 votes went to Kamidori. Hence F/SN won.
Each voting session lasts 24 hours. Here is the Board. You can bookmark and check back every now and then.
I wonder if they’re going to have subsequent brackets to put stuff like Canvas 2, Hoshimemo or Ef –A tales of the two- in? I can sort of see why he did it this way? Because if you have a dropdown list of all the VNs and you select the one you liked the most, it’d just become a popularity vote.
