Rocknroms added some doujin PC games today.
Pocket Kanon & Air
Puzzle de Wahhou
Doujin games are made by amateur groups, not by official game publishers.
And many of doujin games are also adult games. Actually, the original Kanon and Air (not Pocket Kanon & Air) are adult adventure games.
Are Doujin/Adult games allowed?
Should they be separated from official games?
