Let's discuss the ending condition:
At turn X, you win the game if you have accumulated 12-X points with your team
At turn X, you win the game individually if you have 13-X stars at any point
This way, the longer the game is, the more balanced the teams need to be, the higher the pressure is on the alliances to break. Also, in this scenario, I think we don't need to differentiate between the number of players? At any point, you can calculate whether the team will win before an individual of the team wins.
When is the pressure on the alliances highest:
Towards the end of the game
When the alliance has one big player
When the team is losing in accumulated points
When the teams have a balanced number of stars
When is the pressure lowest:
In the beginning of the game
When an alliance is balanced
When the team is winning in accumulated points
When the teams have a very different number of stars
It has as benefits:
It is easy to design clearly, only a single track on the board left
It benefits balanced teams #10
No more artificial end after 10 rounds.
The rule has low complexity, but it makes the game far more strategic and complex
Games with a clear winner are ended earlier
Games can start with piloting of new players in the first rounds, but this is over later in the game
I also do not immediately see room for backstabbing. Only in the last rounds it might become relevant, but I reckon the odds of getting there are low.
