@xᴇɴᴏ:: Ahh, okay good to know. Thank you~
@ꜱʜᴏᴛᴀ:: Actually N+C's stuff is really good. I played DMMR: Re a few months ago, but tbh it was kind of confusing the way they set up the character selection and routes and such. However! I'm playing Togainu no Chi as we speak, and I didn't even realize that it was a game, let alone made by N+C until I saw an installation guide for it on here a few days back. Seeing as how it was one of my favorite anime when I was younger, I was ridiculously happy and just had to get it. It's waaayyy less confusing than DMMR's set-up, plus an amazing game with stunning art that's better than the anime's.
As far as how accessible it is, extremely so. AarinFantasy has a lot of their stuff, and you can download the game and see how to install / play HERE. I highly recommend you play it if you're into mature BL games. Fair warning though, it's super gory and has some fucked-up shit sprinkled around. So...pretty much the same as the rest of N+C's stuff hahah. As far as fanservice and ero go...the only fanservice it has is boy x boy, and there's a shitton of erotic scenes. I'd say waaaayyy more so than normal Japanese VN's.
Hope that helped clear things up!
