If he ever releases it, because let's be honest, Eternum is what is giving him money at. Even if I'm from the OG group of fans who support his work since literally first release of Oailt, I understand his reasoning of just caring about Eternum. Even if many fans remain, the jump in number of supporters after Eternum first release was outstanding.
I'm happy for him, he deserves due the care he has for the fans, but I don't see him bring again something that doesn't bring him money, unless he puts it on platforms like Steam or Gog,
Tales of the Undending Void is the for example. I would probably buy it, but many others probably not without decent publicity.
At this point, only if remastered it it maybe would be worth, which I reaaaaaaaaaaaaally doubt that will ever happen. Oh well, I'm sad we won't have more Carla content, but I'm still having a lot of fun with Eternum anyway, so I can't complain.
