I fail to see why there is a problem with being registered to vote. If guests can vote, how would you check that the same user is not busy casting five hundred votes for the same game otherwise? On the other hand, you can check IPs and the like for registered users, so someone voting with multiple accounts would be a lot easier to spot.

Trust me on that one: some players just love clickfests, as evidenced by the DROD forum has a lovely bar that has been clicked on quite a few times.
