Ah. That makes me more excited to dive into C;C! I'm in the prologue right now and things are heating up quite quickly which is a suprise. I'll try out NOAH when it comes out.
So is O;9 rumored to live up to the SciAdv reputation? Looking at the anime trailer and VN info page, it's not getting me too excited. But I'll always give it a try.
I haven't played the O;N VN but I've read most of the light novel that it's based on and the story is... okay. It's very short, maybe a hundred pages or so, and it's about paranormal investigation. If the VN covers both the first and second light novels then it might be enough, but it's a weird situation - the SciAdv VNs are 30-50 hour affairs and O;N was a light novel and an anime before it was adapted into a VN... so honestly until the VN is out on the 9th and we get to play through it it's hard to say how the Science Visual Novel series compares to SciAdv. Luckily, if it turns out to be lacklustre it shouldn't be that big a deal because it's a different franchise, so the impact on the SciAdv story which people know and love would be zero.
