Thanks for the replies. I have a question though, does the dev intend to finish the main story first then do the sidequests? Or does he intend to leave finishing the main story until the end after he finished everything else? Or did he not say his plan?
After that comes the final open world, which is more substantial than the others, comparable to how many JRPGs open up new content before the final boss. There will be sidequests, including a personal one for every harem member, but also some optional content that's important to the central plot and ending. This is also the stage where I'm sure some people will say that I'm dragging out the game for money, but all I can say is that I believe everything during this part is important for the game as a whole.
Once that's done, there's the climactic sequence, final optional dungeon, epilogue, and postgame, as I promised in the roadmap
is the public information we got last year though I will say the last war thing went to three updates instead of the planned 2
and to paraphrase info on the patron status updates the game is close enough that it is possible to finish this year but more likely next year as it not unreasonable for it to finish in 2022 but sierra worries that it won't get down(as well as unhappy they didn't meet their personal goal for last year by 1 update)
