questions of this kind:
so, if the tournament is indeed a race-based clash, how will the winner be determined? (something like: among humans - 1st place - player X, among necropolises - 1st place - player Y, etc.).
How will the overall winner be determined?
There will be winners among the races and an overall winner.
The overall winner - in the case of a knockout tournament, it will be the last one remaining; if it's a round-robin tournament, it will be the one with the most wins.
And what if one player represents a certain race, while others represent several?
Nothing terrible :) it won't be a problem.
We can also consider the following situation:
let's say player X, representing humans, defeated player Y, who hasn't lost at all..., but X himself lost to everyone else... - how will the strongest be determined in this case?
Based on the number of wins (possibly in the top 3, as some races have advantages, which is why castles are being eliminated; then an extra argument will lean towards the top 5 :))
