I must be imagining things like threesomes, additional sex poses and dialogues (or more dialogues in general), more granular and logical taboo breaks, or even much better control over your "business" and its employees.
Could certainly use it, and is being slowly worked on. "Needs" though? No, you need that, not the game. Even with the frequent goblinoid faces it's still a solid game already.
Playes the game based around serums, complains about more serum mechanics...
Not without cheats, unless you have years of real time to grind dates with a single character.
Kind of curious why you'd play something you're clearly not enjoying. Or, hell, just jump onto the devgit, fork off, and start adding things you want. Pretty sure current folks slaving to give us any kind of additional content will be perfectly happy to merge additions that aren't too far out for their vision of the game.
