Well, that's a bit of a longer conversation.
Proper frame-by-frame animation takes a very long time and is very expensive, so I'm afraid we won't be doing anything like that in the near future. It would at least triple both development time and overall cost, if not more.
A common alternative is Live2D, which we experimented with here in Born to Breed. However, I don't think that look would suit Sulcate's art. It has a tendency to look a stiff and can be kind of distracting. I doubt we'll be doing that either.
That said, it won't be quite like Benefitship 1.
I expect that Benefitship 2 will take more use of dynamic camera movements and sound effects. We've experimented with in Sci-Futa, which released earlier today. I'll probably also try to have more unique CGs (rather than a lot of alts) to help give scenes an extra layer of energy and variety.
I hope that answers your question!
