I myself always thoroughly enjoyed this game, first and foremost for its humor, and that never changed.
It's understandable that a lot of people weren't exactly thrilled that Nikki was never going to be a love interest in the story, would it have been nice if she was? Of course. But Sumo made it VERY clear from the beginning that she won't be, and I made peace with that and accepted it. I don't know how after two years people still act surprised, and it's not like Sumo and others haven't mentioned it multiple times over and over.
I actually give Sumo mad kudos for sticking to the guns and writing the story that it was set out to be, rather than give into the audience's 'demands' and requests, it's like "is the dev writing the story or you?" kind of thing. Besides, it's impossible to cater to everyone's needs and likes, some will love the story, some will hate it and some will be indifferent, that's always the case, so it's better to write the story YOU want.
