Finally, something useful, IronAxe, well done! I don't even know what to add; for now, I agree with all the points. Yes, Tournaments should definitely be held every 2-3 months – "official" ones, meaning prestigious ones with a large prize pool. Moderators should be in charge of these Tournaments.

Regarding the timing, I don't object because the schedule would be too intense if it were once a month. Once every three months is a reasonable timeframe while we test the idea and everything settles down. After everything is stable, we can switch to once every two months (which would result in 6 qualifying Tournaments per year). We can now start thinking about what the minimum qualifying score should be for the final Tournament, which is very difficult because, as I understand it, the Rating is calculated based on the number of participants in the Tournament and their placement. But what if the number of participants fluctuates significantly?

I like it too :) Unofficial Tournaments will appear anyway. But has the admin seen all this beauty? Has he evaluated it?

While we wait for the admins, we can get a little closer to the details – let's discuss the numbers (but let's try not to overcomplicate things so we don't get confused).
We can all see the Tournament table from the first Tournament. I would calculate the rewards like this: take the Rating and multiply it by 100.
For first place, it would be 5000
For last place, it would be 800

In your opinion, how much should ONE plot of land cost with this system? Considering that there will be 6 qualifying Tournaments per year.

And another important point regarding preventing the number of plots of land from becoming infinite.
We might not even need to draw a map. Because it could turn out like in the history of the Imperial Bank – there won't be enough for everyone. :)
On the other hand, we believe that, in principle, there is an infinite number of plots of land. However, we need to link the maximum number of plots of land that a portal participant can have to their Title. This would simply be another parameter for players – the number of plots of land. A peasant cannot have more than one plot of land, a Knight cannot have more than two. If desired, the map can be drawn as players acquire plots of land (but I think there will be difficulties with the map; who will be in charge of it?). It's easier to simply write that player IronAxe, Title: peasant, Plots of land: 1.
And in the internal wars, fight not for acquiring new plots of land, but for destroying them from opponents, in the case where the Title does not allow the player to annex the conquered land.
