Please, no mini-games. I absolutely hate mini-games in these games. Puzzles are better.
I am also sick of the utterly ridiculous amounts of grind people are putting in their games now. It's nonsense. These games are supposed to be fun. Tired of waiting for a mod to skip all the grind so you can actually ENJOY the game. No, repeating the same thing 10 times over to level up is NOT fun. Repeating a conversation over and over with a small amount added each time is not fun. Having to do things on a specific day at and specific time in a specific way is NOT fun.
To each their own I guess. Personally I sort those adult games in what I call "afternoon games", "evening games", and "night games". In the afternoon I like playing an actual game which may or may not include mini games and repitition (grind) or, like here, management elements. And yes, that is fun to me. This is an afternoon game and I am happy that some people create them. If you don't like afternoon games, there are enough evening and night games out there.
("evening" is more story driven, should also be more than just having sex but some major arc not only about getting the girls and/or meaningful decisions, not just jumping from sex scene to sex scene, "night" are just a fun romp without depth. And no, I don't necessarily switch games at 7 pm, it ain't that clear cut.)
But in the end it's not "nonsense", it's a matter of taste - both by the dev and the player.
