What do the official forums and the fan forums want?

First, the result of 13-10 (I'll add my vote to the VT players) indicates a division of opinions.

Isn't this news?

...Secondly, I didn't want to emphasize this too much, but the weight category of VT players and SOD players is unfortunately incomparable (if we take into account the track record of those who expressed their opinion...).

Never mind, we'll invite the Danish king and balance the track record...

Unfortunately, adopting the SOD version will lead to the fact that this tournament can be called anything, but it will not become a final, nor even a battle at all; "sandbox championship" is a more fitting description.

But we are not claiming to be the championship of the universe; we want an Open Sandbox Championship. And what to call it is a secondary matter. FB is the final game, its conclusion; this is where the players will show their current level, and we will draw some kind of intermediate conclusion.

...I suggest looking for compromises, for example, by trying to divide the templates/versions. For example, L+U and play less on SOD, HL on VT.

But then the tournament will be for three players (see the voting results). The words "only" appear in the first and second points.

And if we're serious...
There is experience in running tournaments on two versions. And it is quite sad. When players who do not want to compromise on this issue meet (and this was practically every time), there are withdrawals, grievances, or non-gaming victories. It is especially unpleasant when this happens closer to the final.
Therefore, I came to the conclusion that in the matter of versions, it is necessary to decide immediately in order not to upset the players.
