The ideal progression would be to prioritize giving the game an ending. And from there expanding with additional routes, locations, and minigames.I don't know how you arrived at this conclusion from what I said so I'll try and be more clear.
These games almost never get finished. The reason for this is they keep building stupid "gameplay" bullshit like your locations when all anyone wants is the porn. So no, I do not want expanded locations when these developers can't even put out enough sex scenes to fill their game because they spend all their time on 'finding spiders' or 'doing chores around the house'. The best version of the Big Brother game formula is one with more sex and less tedious horseshit so as I said I do not want development time spent on new locations when they can't even finish the current ones.
But most hentai devs keep getting for granted that once the player manage to fuck one character then the player completely loose interest on the game. And so they purposefully keep this "blueballing" going on. Hoping that patreon donors will keep wasting money for a game that never deliver.
The sad thing, is that this strategy actually work and dumbasses make the dev gain thousands of bucks monthly for a game that after 5 or more years still doesn't allow the player to fuck one single girl. Often giving them "dream sequences" and christmas/halloween bonus scenes as a pathetic and insulting way to appease them.
This trend will continue until finally people will not wake up and tell developers "want my money? You'll get nothing until my virtual penis doesn't go inside some girl". DO NOT DONATE YOUR MONEY FOR A GAME WHERE THERE IS NO SEX.
It's the only way.
