以前よりはハードディスクの必要容量を抑えました

The hard disk space required for Ver. 0.25 or later is less than before, depending on the number of years of play.
For games newly started after Ver. 0.25,
The required hard disk space is now only about 17 GB for 100 years of play.
We realize this is still a lot, but we apologize for the inconvenience caused by our lack of power.
