From what I gather from the broken English I think this is the last release of Marina.
Ah ya that tweet is pretty final I suppose haha, it also makes sense as to why we are seeing these "voice drama's" now and without the support of the games original creator/writer. Basically they are like fan discs, a "what if" scenario. The Marina series made a strong point that Marina was actually against the whole thing of sharing and so cheating was far from her mind. However a lot of fans WANTED more hardcore elements to the series and I think thats why we got these "limited" voice drama's involving cheating.
That said they could have actually put more work into it and made it a short "fan" game like the gaiden series, but I suppose without the original writers help they couldn't.
Also as for Hiroto is makes sense to use him for this "scenario" since the other men she's interacted with don't really "fit" for this scenario based on the the games canon.
Still based on the setup from gaiden 2 I could still see a Marina 4 maybe a year from now - like a sudden surprise announcement. At-Sakura knows it would make money clearly...
My fan game announcement: (unofficially announced here pending its own thread)
Regardless I have my own announcement, I was debating on translating the series but damn that would be a big project now - I'm still thinking about it BUT I've decided to go forward with my own fan scenario using resources (char art, backgrounds, music from the past games) and build it with TyranoBuilder.
More details to follow in my official thread but I thought it worth mentioning here since it will involve NTR physiological elements.
The basic plot setup is "Kenji can't let go of his fantasy of sharing Marina, but those days are long over. Still the fantasy persists and so he asks Marina to "pretend" that she is being shared, which she agree's to seeing some fun in it. As Kenji you will start to wonder if shes crossed from fantasy to reality, explore daily life together and meet old friends."
The basic idea is that's a mystery ntr game leaving the player to discover the truth and will feature multiply endings that all "align", with some great plot twists and surprises you won't see coming.
Obviously it won't be voiced (unless I can get the original VA on board lol...probably not gonna happen but stranger things have happened!) but thats it and work's already began on it.
I feel it will be something both NTR and netorase fans will enjoy.
