pretty cool game, definitely worth playing if youre into rance, and you probably are if youve gotten all the way to VI.
i think one important thing to say about this game though is that it can feel absolutely exhausting to play because of the stamina system, where whenever you enter a battle every party members stamina will lower, and when it reaches zero theyll be forced to go back to base. the game has a max available party of 16 people, allowing you to replace these party members, the problem is when youre mid gameish a lot of these wont be very good and youll be stuck using very subpar party members for most of the map. this probably wouldnt be a problem if the enemy encounter rate wasnt so high.
that being said, id probably play it at least for the story, it's the first rance game where the story takes on a more "serious" tone, although obviously the game still has the silliness that every rance game has. It definitely is the first Rance game, other than IV maybe where it feels like the story actually has stakes in it, it's pretty cool.
really, the gameplay and story tone feel more like a sort of stepping stone kinda into the more modern rance games like sengoku and quest, it’s worth checking out if you enjoyed the previous games definitely
