As for the save files, the problem for me is sending and downloading such large amounts of data. If a single file for an offline tournament is 500 KB, not everyone will be able to send the entire walkthrough. Unless they burn it to a disc and send it by mail... And in general, our internet connection is very, very poor.
I fully understand all the problems with the internet, as I am in a similar situation myself, and the prospect of downloading 50 MB of save files is not at all appealing. I repeat - only 1 save file needs to be sent - the final one. And if I or the players have any questions, then it will most likely be enough to simply provide a detailed description of the walkthrough.
I am uploading the tournament map.
