I have a question about Avereni scoring in last winter. In instuction is offmap legions -6 or allied tribes or citadel -8. We choose better or worse score to obtain a final score? In middle winter the both condition have to be fulfilled to avereni wins, s o ithing we shoud chose worse score.
Correct. From the rules:
7.3 During the Final Winter (emphasis added)
If play reaches the final Winter Round (2.4.1, including game end via the Optimates Event) and no Faction has met its condition set forth in 7.2, the Faction with the highest victory margin wins. A victory margin is the amount a Faction is beyond or short of its condition—
• Romans: Subdued plus Dispersed plus Roman Allied Tribes – 15.
• Arverni: Lower of off-map Legions – 6 or Arverni Allied Tribes
and Citadels – 8.
Second question , is the tie in final (or even in middle winter) solved?
Yes. From the rules:
7.1 Ranking Wins and Breaking Ties (emphasis added)
Whenever any Non-player Faction passes a victory check (7.2), all players lose equally. Otherwise, whenever any player does so or if none does by game end, the Faction that reached the highest victory margin (7.3) comes in 1st place, 2nd-highest comes in 2nd place, and so on. Ties go to any Non-players (8.0), then the Romans, then the Arverni, then the Aedui.
