Well, it's really sad to know Succubus Covenant is dead (abandoned). But WHY SOME PEOPLE before write anything,,, why not they just try to read Zion_of_Olympus Twiter account? That's because it clearly says THEY -not just one developer- ...I've said it before but a general problem with western devs is their random need to just do as much as possible with no clear objective. So many developers like Zion end up making random games and side projects making the mainline product look abandoned or on hold. They bite off more than they can chew.
I think realistically the fault is 50/50. Zion is at fault for poor management of development and a lack of focus as you say. You could also argue that Zion should of been more familiar with the interests of the people he works with. However things such as key artist injuries that stop them from working is simply out of Zion's hands and something I would never blame Zion for. I am also not a fan of the hostility some people have been giving Zion. Yeah I understand people are frustrated, more so if you actually gave money but its just unproductive.
My real thoughts are that Zion could make a easy comeback if he gets his head in the game and just works on Succubus Covenant. I really don't want to see any more mid tier side games like Eden Crest.
Idk what would happened but that team (Zion of Olympus) is not a serious company or perhaps that problem is not so difficult if we get not every people dream as a child to develop porn games, and that " philosophy of lack " if is a team is close to the washout
