In the age when we have companies in the west buying Japanese hentai games and decensoring them I just got to wonder. Why has no one touched the Taimanin series yet?
Ah, Black Lilith is kinda cancerous in that regard. They tried to throw out TA1 on Steam with the most schizo approach possible (free intro chapters with the plan of releasing the game bite-sized and you needed to pay for every chapter in an already short VN, don't remember if they even went through that one). Also, flat-out stole the fan TY1 translation - or maybe that was their subcontractors, who knows -. They tried years ago to dump on the western market some older titles, but apparently they sold so badly they didn't see the point.
TABA in ENG is pretty much a afterthought and Action Taimanin in Global is purposefully gimped to make filthy foreigners pay more to grind more.
I somewhat have the impression they don't like the foreign market much. Just an impression.
