Very few games achieve this for me where i'm looking forward to the next update for the story as much as the content. The one for me at the moment that does this is eruption imminent - the characters personalities are just so well done that it kind of sucks you into that world
These days it's probably graphics, I struggle with the grainy/dated look now that didn't bother me a few years ago.
After that, it's about characters and dialogue - make either of those boring and it can quickly feel like playing the game is a grind
Can't remember a specific time where it's distracted me from the game story.
Oddly enough I used to find it more distracting when all female characters seemed to share the 90% the same clothes across games
Aimless grind in sandbox - don't mind those with clear direction and good in-game logs etc
Too many side characters to drag out updates and avoid progression with the main LIs
Potential to be a top game, but is slightly risking the too many characters trap.
Also not a fan of missing out on content too easily when it is not clear that one choice with character A will lock you out of content with character B
The sweet spot is about 5 to 6 girls who's characters and stories have been well developed, always hotter when there's a 3D personality attached to each girl
Not sure if you're concern is it's too quick or too long but I would say there is a good amount of content without being too grindy like some sandbox games. Absolutely worth a go if you like fantasy genre
This one is great game to play if you want a break from all the slow-burns. Models are great, story is silly but just used as a vehicle to get to the good stuff without messing around
