Mashirori

Not only it's very long, it is also one of their oldest titles. It's much less riskier to launch a medium-sized title by Urobuchi than one of the longest VNs of all time written by a nobody no one is familiar with in the western community is familiar with. Not only that but it has a very slow beginning. You'll definitively need to be patient. I wouldn't say it's "much more renowned", though. Its score in EGS is 80, the same as Django. Also it's nothing like Steins;Gate, or any title of the sci;adv series. On a side note, I've been reading Oretsuba. I'll write my thoughts about it after I finish at least one of Hawk's routes, but it's shaping up to be in my top 3, definitively.
