There is no grinding whatsoever in Harem Hotel. Every character event is reliant on a single *talk* action or auto-event. There is no grinding in Mythic Manor. Both games use a system of money but aren't totally reliant on it that it needs to be done constantly. With this game VIRTUES, you must grind to play the next character event on every character. So to play just one event for all 7 characters, you would have to grind up to 35 times since the majority of events seem to trigger at levels divisible by 5. This must be done for each scene, each character. A big difference. Repeatable scenes, are almost non existant.
The definition of harem is a household of wives or concubines. Take a look at Harem Hotel. All the girls reside in the hotel, same with Mythic Manor. Same with Sistery Lust. Same with a House in the Rift. Same with any other harem game. Now take a look at what is going on here with this game. This game has an MC that behaves like a virgin loser for the majority of the game.
The problem with the UI is it's bland and unimaginative. You click on an area and it's mostly just text with a couple of renders. You spend the majority of the game time on the overmap, which is just plain cheap and of minimal effort. Other games you are immersed into the world.
