I decided that because the OP has always stated that previous works were accepted the people who had posted before would be able to be in the comp.
I didn't think there would be much bias in voting.
I understand the concern and I have had another entrant PM me the same question. I wrote a ~4 paragraph explanation. If anybody would like a copy PM me. The person who asked is also an anonymous entrant so I would need to edit somewhat.
As for the competition...voting will be tomorrow as I had technical difficulties tonight (hence the post at 1 am my time) and can barely stay awake. Voting will be extended an extra day to compensate for this and the US Memorial Day holiday.
By the way the deadline has closed. I will wish everyone an early good luck.
Now just donates stuff
I have been playing Beautiful Katamari and MGS4...sorry
