I don't see the point in selling censored games when you can easily buy/pirate the uncensored version elsewhere. it's bad business and I will not be buying anymore vns from gog or mangagamer. especially mangagamer.
Your post is seriously ignorant. First, the version sold on GoG is not censored. Go check vndb if you don't believe that the game was originally all ages. And standalone adult version was never released in Japan, they only offered add-on pack.
Second, Mangagamer is the best English language VN publisher when it comes to releasing uncut versions. They offer full/uncensored versions for each game they translate. Even with this VN, eden*, you can buy adult version at their store: http://www.mangagamer.com/detail.php?goods_type=1&product_code=125
They can't sell it here due to logistical and legal reasons, it's not a voluntary choice.
It's just ridiculous to hate Mangagamer for this when they are the only English VN publisher who consistently offers uncut versions for their translations. If you want to hate someone for releasing censored versions, then you should at least do proper research first.
