Can an Eternum update possibly ever be long enough, though?
I'll answer seriously... You're going to have to always find a balance of quality and quantity. ESPECIALLY with adult gaming as a genre. Remember that in the West, this is a niche market whereas it's more fully developed in Japan over some countries like Korea.
So you need to provide a good sustainable production line to the community which keeps your name up over taking too long with quality control (What a Legend is going through this due to unforeseen circumstances) and quantity of updates.
Around here, I've seen legal fights just tear up teams right along with some devs picking up the pieces of a project to complete it for themselves and satisfy the community.
Long story short, there's just no right answer. You do the best you can with the resources you have and figure it out as you go along.
Now on the funny side...
All I know is that the Princess is getting Orc D.
