The ninth stage of the Kanigem Tournaments

Isn't it possible to watch replays only in the 4th game?:o
P.S. Sorry in advance, I just don't know anything about other games besides the 4th.

In the 5th game, you can't watch the execution of a turn on the adventure map, but you can watch the execution of a specific battle if you have the corresponding save file. In the 4th game, you can't watch the execution of a battle, but if you have a save file from the end of a turn, you can see how the player acted on the adventure map.

You need a save file from the end of the game day. Then you choose "Game Menu" - the red flag. Next - "View Turn".
P.S. This is how you check any turn of a competitor in the 4th game:D. If you set the army speed to medium in the settings, it's even better. And you can pause and see at any moment who, where, when, with whom, and with what artifacts :D

Absolutely correct. Pause - spacebar. And if the reviewer starts to doubt whether any of the battles can actually be completed, you can request a save file for the beginning of that battle (participants must have such save files). After that, you can try to complete this battle yourself from that save file. If it doesn't work, you can ask for verbal explanations about the tactics in that battle.
