LP uses the concept of 'PD' and 'in-game day' together, which confuses many people and I have been confused many times.
That's why I write 'in-game day' as the main and PD as the sub.
This is because the date that people come into contact with through the game is literally the 'in-game day'. (Currently 21st.)
As you can see from the chart, the game development period is continuously increasing, and the last 20 days (PD13) took 777 days.
If it takes 2 years for the production period per day (PD1), this game is planned to last 37 days (currently 21 days), so it will end in 32 years from now. (16x2=32)
