Wanko to Kurasou
You guys used to have a link to the fan translation way back in the day
Ivory's (the developer) official website has been down since about 2007, so not sure how licensing will work for that, but getchu still has it for sale
Wanko to Kurasou
Sakura Machizaka Stories Vol. 2 "Sensei ga Oshiete Ageru!"
Another Title from Ivory, it looks pretty nice, and is also available for purchase from getchu
Sakura Machizaka
Sengoku Rance
Another great game, that I originally learned of on Fakku in the old days
Your Diary + H
A great VN by Cube, it seems like cube has merged with a few other developers http://www.cuffs.co.jp/main/.
There is an all ages steam release, but the translation is garbage tier.
Hopefully you guys can get a 18+ release with quality translations
Koi Suru Kanojo no Bukiyou na Butai (Koikano)
Another game from Cube, the name basically translates to "All the world's a stage, and all the men and women merely players."
Would love to see this get a English translation.
and as has been mentioned by previous commenters an official CM3D2 translation would be awesome.
