There is no way to make Attribute Points or Production Points increase faster.
Every 110 ticks (18 hours and 20 minutes), an employee becomes eligible for improvement. To use RPG-style language, a 20-sided die is rolled for each eligible employee. If the roll is less than 10, no attribute improvement occurs and the employee's counter for when he becomes eligible is reset.
If the roll is 10-13, he will gain 1 point. 14-15: 2 points, 16-17: 3 points, 8-19: 4 points, 20: 5 points.
If a 7-sided die comes up 7, the employee's profession points are increased by the number of points already determined. Otherwise, a 5-sided die is rolled to determine which of the 5 attribute points are increased. No attribute can exceed 100 points.
Once the process is completed the employee's tick counter is reset to 0.
There is a chance an employee will gain points after he has accumulated 40 ticks but before he reaches 110 ticks. This is determined by selecting a random number between 40 and 110. Any employee at the exact number of ticks matching the random number will go through the process described above.
An employee's tick counter does not increase while he is in training, absent, or in the head office.
Any person will work in any building, but only people who can drive can be in a vehicle.
