These two entries:
Labyrinth of Grisaia - Eroge Download | Eroge Download
The Labyrinth of Grisaia - Eroge Download | Eroge Download
Former is the 18+ version, the latter the all-ages version.
It might be worth to keep both entries(?). But unless one checks the comments/tags below there's no way to distinguish which version is which as the description/title is identical. The 18+ version is the one listed on the downloads list. It would help if they were inter-linked in 'related links'.
