My thoughts:
- Name the tournament "World War 3" and divide it into two blocks, let's say, Blue and Red!
On one side - Europe (you can assign Ukrainians to help them), on the other - the former republics of the USSR, you can also add the Chinese to our side.
- Play one game per day, with mandatory two-way streaming (i.e., only recruit those who are willing to stream with at least audio commentary).
- You can provide for a hot swap in the rules (create a table of 1st, 2nd, etc. replacement queues) so that the evening match takes place in 100% of cases.
I liked it.
