Then it will get better or at least be more enjoyable.
No, it's not. This "struggle" was annoying, nothing else. Most story arcs have nothing to do with Eric in the first place, he is only present in very few arcs and ... I don't miss him in these. It's a lot more fun to find out how to manipulate Alice (first) with liquor pralines, with pranks and some nice actions, than interrupt anything that Eric might or might not be doing. Gladly, he doesn't do much, so one has not to bother too much. If you remember to poison him on a regular base you hardly notice he's here. The struggle defines only a very small part of the game which can be ignored easily.
What I am looking for is not a obsolete struggle with a virtual character, but fun writing, a little bit of finding out what to do next, discovering new events and opportunities, maybe also a bit problem solving. For all that I don't need a Eric. Back in the Days I found Man of the House very nice. Again ... no Eric.
You mentioned something like the game being a VN without Eric. The gameplay mechanics have little to nothing to do with it's content. There are VNs with arch enemies and there are free roaming games without.
BB is actually one of the games, that almost go towards the adventure game play, more than most free roaming games. Find out what to do, look for items, talk to people, use stuff. What I miss a bit, are more combinations compared to the old aif text adventures. But since everything has to be rendered these days, that won't come back. Did you notice that I didn't mention Eric here? He is not part of the gameplay mechanics, these won't change once he's gone.
