At the rate this game is going, yes. It's unfortunate that Runey lost their dad and everyone would have taken time for that, it's completely understandable, but if you look at the raw facts, the game has been developed for close to 6 years now and has had 18 major updates? I mean... how many other amazing games with roughly the same amount or more of content have been developed and finished in that time frame using both Honey Select and Ren'py? Everyone's method of work is yeah, and at least it's nowhere as horrible as Summertime Saga sure, but that 2069 window for the final complete version doesn't seem like too far of a stretch realistically at this point.
Just how many more updates are you basing your assumption on?
Runey, a while back said that there would be 4 or 5 more updates for Harem Hotel.
Except for this year, because of the loss of his father, there has been an average of 2 to 3 updates per year.
If we assume the greater number of updates left to go, plus throw in one more, just in case, and a return to the 2 to 3 updates per year, then Harem Hotel will be completed in about 2 to 3 years, at the most.
Even if there were another year or two with only one update, then it would still be completed in 5 years, or less.
If you are so upset about the slow release times for the solo project that is Harem Hotel, I suggest that you play some of the other large games that you referred to instead.
Most games have development teams, so their ability to create releases faster, sound like they would be a better match for you.
One person doing the graphics, and possibly another person doing the animation work, and if you don't already know this, graphics and animations take a long time to render. And that ties up a lot of a PC's processing power, even with a high end graphics card.
One person writing the story.
One person doing the code that ties everything together.
Then you have to factor in the time to test everything, and fix bugs found.
Runey does not have a team doing that for him, unlike 99% of the game creators on F95 who work as a team to create the games and visual novels.
