Bank Time Limit
Bank time is a under use option of this game.
With a Bank Time limit, you can make a 1 day game with a bank of 6h but limit to 2 days bank. Its almost like a 3 days game but faster.
The issues is without a limit, someone can bank many days and use it as vacation or just to p$#& other player.
You can also choose not to join games with large bank times.
