Alright, update time! First, I have a shutoff time for the contest - it will run until some time in the afternoon (GMT) on Sunday. Unless I have to work really late. Whatever.
Second, I really want to get these prizes out in time for the Christmas break, so please note this change: unlike last year, if you're randomly chosen but don't really need your game soon and would rather see what the sale has to offer, you can PM me before the end of Monday and tell me to wait to buy your gift code and see if there's a different game in the price range that you want. So this way, if you want a game soon, you can get it soon, but if you want to wait and see if the sale will offer something you'd rather have, that's fine too.
Thirdly, let me answer two questions that have come up several times:
Yes, you can wait to decide which game you want until after the random choosing is done.
Yes, you can change your answer to one of the riddles. I'll only accept the last answer you submit, though, so make sure you don't want to go back to a previous answer, later on.
There you have it. I'll post again when the contest ends, and then update that final post with the results of the random draws. Good luck, everyone.
