Let's reason deductively... We need to set goals.

4. Where do we get these teams? We need to attract foreigners!

Here are the goals, in my opinion. Based on these goals, we need to define the concept and tasks.
to Nagan:
By allowing people to set their own goals, we risk chaos and disorganization, with everyone going their own way, which could lead to a significant potential conflict...
More specifically:
Yielding to Bay's "ultimatum" regarding certain games on TE-full is a dead end for the interportal idea, and it limits the potential scalability of the project. It moves us away from the goal of achieving a truly international status. Instead of expanding contacts and finding common ground (even Balance, as one of the main templates, is a good sub-task – developing Universal Rules), the best players in the World are drawn into a local, closed-off (well, 20-25 constantly playing, and even if it's 40 players, it's not a big loss) version of TE-full. This is wrong, and it won't help us achieve our goals.
If the Bay players (some of the strongest players in the Russian-speaking internet, without a doubt) really want to play their homegrown version (yes, yes, I know, it's sacred and untouchable) – let it be optional, not counted in the overall standings (for example, three TE players, not counted towards the score, as a way to popularize their vision of the game). And those guys from Bay who aren't so sectarian – let them form their own team on SOD (which the rest of the world plays, and that's a fact, even if they have to rage about it).
In the worst-case scenario – if the TE apologists win and don't compromise – we play some games on TE (while forcing both HW and World to frantically look for supporters of the local version – bending over backward, so to speak, out of respect) – exclude Bay from this interportal. It's bad, but going along with their demands and losing sight of the interportal's goals is worse. Think about it, Nagan :)
