According to the message I received from Discord, this work will be revived. Below is the author's reply. Moreover, the author opened a new page last month on Discord introducing BGR's game history background, and has continued updating the game's story background until just a few days ago. According to him, this game will release a new version in the near future——
“In reality, it's already being done. MOL is being created as a canonical crossover of the previous and middle moments of BGR.
BGR would not start from 0, but where the first part ended, and it would be called BG School War. When I said that you have to start from 0 I did not mean in the story, but in the creation of characters since the files were damaged and it is possible that there would be changes in the appearance of some characters. And when I refer to changes in appearance I don't mean changes in races, but in visual aesthetics.
About redoing the characters in AI is a bit difficult since you have to work on all the Daz characters. Besides, we are talking about 80 characters. Now I was talking to a technician who claims to be able to recover the files but he didn't give any guarantee that it would work well. And if the restoration works, I would not do it in Renpy's, but in Rpg Maker, since it is the ideal program to tell the rest of the story of BG.
I have been explaining that for 1 year. The damage was very great. People accuse me of giving up the project too easily, but the truth is that it hurt to lose 5 years of hard work. I want to resume BG, but I want to finish the story of Mansion. Besides, this new game is helping me to learn everything I need to know to resume BG. The last Mansion update was considered a failure because the system that was being worked on turned out to be useless to implement some story events. However the programmer understood his mistake and is now working on a more flexible way.”
