It does make sense.
You can look at it two ways.
1) They were judged as a whole.
2) They were judged by piece, and then weren't allowed to place a second time for another piece, thus they appear only once on the list, anyway.
We actually chattered about what we liked the most with each other sometimes before the votes opened, etc, and from what I saw, I don't see any placing differences no matter which way you decide to look at it, as, as we said earlier, it's a Promo Contest, and one really strong piece is still going to make us vote for that person over someone who theoretically has many small pieces, even while looking at it it as a "package" of sorts.
Everyone seems to have issues no matter which way we judge these, and we have tried a few different ways in the past, so I'm just going to go make some food.
Edit:
Food downed!
In the short run, it was in an effort to prevent what caused so much drama with the Party Screenshot Contest.
When we get a bunch of strong similar quality entries from one (or even two or three people), and we vote on only one entry, it forces GMs to vote for the one they personally like best, even if they are all equally strong and even if all the GMs like them all.
What happens here is that due to slight changes in GM preferences and the such, it easily comes about that the votes get spread around over the large amount of entries, and as such, they all end up placing really low, whereas the single, potentially not-so-strong entries come out on top, simply due to the fact that there is only one to decide between.
While not directly the same as what happened in the screenshot contest, it is close. Everyone was disagreeing on which they thought was strongest, with drastically different opinions, so an entry that was, admittedly a bit lower down on a lot of GMs lists won. Then you guys all tried to flame us.
The other way this could have gone was that GMs only tended towards a couple of the entries from the people with multiple, and put them high on their votes list.
What happens here is that these people start placing multiple times, and we really didn't want that, either. Spread the love as much as we can.
There were a few other changes, such as the way the points voting system worked, but overall we wanted to try and preserve the strongest entries coming out on top, while not filling the prize list with duplicates.
We basically chose which entry we liked the most, and slapped the submitters
name to it, rather than the piece itself.
