What if everyone creates a save for the other participants? Meaning, he creates a map, launches it for the first time, saves it and sends it to all others (or posts it here). I suggest that everyone engage in Mapmaking so that during the tournament we can evaluate the strength of players under different conditions, playing as different races with different victory objectives. IMHO.
This is certainly an interesting option; the only problem is that not everyone will be able to make a map (if they even want to). And as for the deadline by which the maps would be implemented (made), that would also take a lot of time. Moreover, initially people signed up on the basis that they would Download (whether it's a map or a save) from our beloved portal, and now another little problem is being thrown at them...;)
In any case, AlexeyPank, thank you for your proposal, which reflects your interest in the tournament.:)
