The rulebook suggests that if some players have their forest floor uncovered fully, they lose. This is never the case in our group.
Because the abundance of Treasures, all players are able to cover their floor, once they see someone closed the game. What are we doing wrong? :)
The tie-breaker of nuts is too weak, in most cases that doesn't decide, either. If we house-ruled a secondary tie-breaker concerning the forest animals, what would be the best way to determine winner?
1) The one having most animals, or
2) the one having most forest squares covered by animals?
(No. 2 would be my preference.)
Could you tell me with how many treasures your group finishes a game? Is everybody playing ONLY nuts/feathers in the rounds before the end? This sounds a lot like either all members of your group are equally strong players or you aren´t using your treasures.
Because if you have too many left at the end of the game, most of the time it´s a clear sign, that you could have ended the game earlier.
If you really want to use any alternative tie-breaker rules. Use the point-system of the solo-game. But every system like that just increases downtime.
