I tried automatic vote extraction in the Top 72 RPGs vote thread, didn't work at all. There's so many ways to write games like Baldur's Gate II - bg2, BGII, Baldur's Gate 2, Baldur Gate 2, etc...
That's actually not that big of a problem. First, a lot of variation can be removed by applying some simple input sanitation - removing anything that's not a letter or number, converting to lowercase, and so on. Then, what you do is, after the voting is closed, you run your script over the results, but have it print out all the unique game identifiers instead of counting votes, and then manually include every option you're missing. It's not that much work to do this, certainly less than inputting votes manually, and you can probably cover more than half of the spectrum through common sense guesses before you even start.
