I agree with what some said, it is ambitious. However, I'm all for and excited with the number of LIs.
If anything, there are many games where I'm disappointed where my favorite isn't an LI and I have no route with them or ending. So I'd rather have the option for so many unique, great characters, even if it will potentially take longer to complete the overall project.
Even when the remake is completed and we're only moving forward, realistically to finish 25 more chapters on top of the current completed 5, we can expect the series to probably take yeeeaaars to finish, plus there's WIAB...
The only thing I can say is, if you're in it, you'd better be in it for the long haul. I feel it's worth it, and even just Season 1 on it's own is a great story if you aren't a type to be bothered following a series.
