Dokyusei (PC-98)

Dōkyūsei (lit. “Classmates”) is an adult dating-simulation / visual-novel developed and published by ELF Corporation for the NEC PC-9801 on 17 December 1992. Bundled on nine A-to-I floppy disks and playable straight from, or installable to, HDD, the game lets the unnamed high-school protagonist spend the last 30 days of summer vacation roaming town, planning dates and uncovering each heroine’s personal scenario. Success hinges on its now-famous real-time timetable: every girl follows her own daily route, so clues learned with one encounter affect where—and when—you can meet her next. Its slice-of-life focus, multi-ending structure and gentle use of adult scenes helped shift PCs from mere “eroge” devices toward the modern story-driven dating sim, influencing everything from Tokimeki Memorial to subsequent ELF hits.
