I voted too some hours ago (for MM of course, since I've never played FFX) and it will be an interesting battle. ATM it's 50,87:49,13 for FFX, but if you click on the single countries, you can see that the tendency goes to MM in the US and FFX in Europe. And because it's now 7:50pm in Central Europe, it's still high noon in the US and many more votes from the US are still to come (~2/3 of the votes come from there at other polls anyway), so MM still has a reasonable chance of winning!
EDIT: Maybe we should've featured the poll on the ZD main page to raise some awareness but I think it's a little late now.
