Well ... I've been waiting for this game for years.
Gosh I wish more extreme japanese games would get translated!
Needs to be a market for it.
Games like this are niche and generally don't make much money so aren't worth translating.
Maggot Baits got a following due to the dev who got their following from Euphoria. While the content may be extreme in places they are also great writers with interesting stories.
Gore for the sake of gore won't make money, gore with great storytelling behind it will always find a market.
Think about this way, these devs have people reading their work that aren't into guro. Personally i'm more of a vanilla girl. I love romance and love stories and people being happy and not hacked up yet Euphoria was such a great story with interesting characters that I followed their work and loved this.
On the flip side of that I have no interest in something that is pure gore for the sake of shock value. without a story to get a hook on it will struggle to find a market to make it worth translating.
Don't get me wrong, there is certainly a market to be found in the guro community but it's still niche and not bringing in the numbers to make it worth the work.
Give it time though. As more games like this find a foothold the community might grow. Devs like these are showing that it is more than just the gore and opening it up to a wider audience.
While it will never be mainstream it can certainly find a following large enough that more games could be worth bringing over.
Just have to see how well this does in sales. Euphoria did pretty well and I think this is the better story so I hope it does well. It's so much more than just extreme content.
