I think there was a burnout. It took a year for Az to release E9. Other devs, like Philly and DPC take about six months (sometimes longer) for them to release updates. Az said he was even thinking of breaking up the club events into two updates. The first update AT the club with Luis, and the second update when the MC goes home with Emily.
Az said this in late June:
Initial plan for EP10 was to do all of the above as well as the entirety of the next day (which is the weekend). But at this rate I might just wrap up and release EP10 just as the night end after finishing the two branching path. It'll be a shorter episode because of the split path, but it can be replayed to see both, together they'll make up the same play time as a single linear episode.
I don't know what we're going to get to be honest with E10, it might be a two parter, or one long episode. We're not going to really know until he knows for sure. Either way, I'm not expecting this until October/November. if he's 50% done since late April, then we're not going to see this for another 3-4 months at least, but that's my estimation and assessment.
I see Az enough on DISCORD to know he's certainly not milking. It's his first project, and I think he just wants to make sure he does what he wants to do and does it right. That's how I see it anyway. He doesn't strike me as the milker type. Some devs you can just tell by how they relate to the community, either here, DISCORD, Patreon, or whatever else. Az, from what I could tell, isn't that type.
