I don't want Nero to lose or be "corrected". BT3 set up alot of stuff with her and it'd be a tremendous waste to have that culminate in a life's work dashed and her turned into yet another victim as Brandon and Fertech laugh from on high. but it would be weird to have it end with Brandon getting slammed with the consequences of his actions.
I don't entirely know what I want from BT 4 honestly which is what makes me so excited to see what comes next. though granted my aversions means I also stand to have all this hype go south.
BT4 is meant to be the finale and also has alot more choice involved. Part of me is thinking the two extremes mentioned could be potential endings. I would also expect the questions of the nature of Brandon's power to be answered as well, that whole "Nexus of Fate" thing. I don't know how all these plot points come together let alone that and having a scenario where both Brandon and Nero win...
Off the top of my head one way for that to play out is Nero's able to prove that Fertech, Yuland and various others were up to no good getting them in trouble and having them be made to pay for the lives their orders ruined getting Nero their justice while Brandon is saved via some degree of divine intervention or he plays a part in Nero busting all these people so they let him off the hook for now, give him a head start or something.
alternately brandon gets sent to another world by a higher power to go impregnate all the girls of all your favorite franchises
Personally, rather than either of those two, the option that I would dislike the most is for Nero to suddenly do a 180 degree flip on all her beliefs and become a happy breeding slave. For what it's worth, what you describe as the first option is basically exactly what I want to see happen and I hope that's what one of the endings amount to. Hopefully all will be possibilities.
I may be a minority here, but frankly, I am hoping that the whole "nexus of fate" thing DOESN'T ever get explicitly resolved. I think it's better left a mystery, with maybe one or two suggested possibilities without being ever completely confirmed.
I don't think there's really any way you can have the feeling that any kind of justice was done while Reed himself goes free to continue his philandering ways. If anything, he's actually worse than the corporation - you may recall that the company never actually gave him permission to do what he did in BT1 or BT2, they just kind of shrugged their shoulders after it happened.
There's actually a moment (which I loved, personally) where Nero is starting to doubt her initial assessment of Reed as pure evil during the final scene when he describes how Fertech basically owns him. Just as she is starting to feel an inkling of sympathy, Reed squashes it by telling Nero that his motivations are exactly what Nero thought they were, right down to using the same wording she did in her opening soliloquy. Maybe one ending will involve Nero performing a sort of self-sacrifice to ensure that he's locked up and/or castrated?
...
Anyway, I hope that neither the Brandi Reed game nor BT4 get derailed. A few months back, TCW said that he was despondent over certain political trends, and believes that pornography is going to be banned in the USA soon, which would make his game creation business impossible. Hopefully that looming threat blows over and he doesn't get convinced he needs to quit creating ahead of time.
