AmigaLive asked regarding my game submission earlier from Cammy, and Cammy said if updates idea was to make the game to work (a fix) then that would be okay.
I myself did a faster versions update for Amiga versions, I'm not sure if this is calculated a fix anymore, but I anyway kept them separate, that I kept the original files there so that judges could judge based upon the original versions.
However, this is just my opinion, but basically I guess Cammys main idea is to get more games to Amiga, so in that sense I don't necessarily see a problem even if someone does a huge update to his game after the submission deadline, after all, everyone has a chance for that anyway, so its not exactly unfair, well, except for those who actually completed their games before deadline.
But, of course it can be trickier question from fair competition point of view, that if someone actually sent his game to actually compete as the primary motivation, and he made it based upon the rules, then it isn't good if some keep sending major updates to the game. Also, even someone marks it clearly as having been sent after the submission deadline, I do think it will affect the rating positively, so in that sense even more unfair.
I can just say that I don't mind you or others updating the game, but don't know how others, or Cammy and the Judges, see it.
