I played this game a long time ago, I remember that I really liked it for its story and characters but I don't know if it's worth playing again considering it's a long game and the H scenes take a long time to access
Yeah, I've also played the game when it just "released" (damn, it was, like, what, seven years ago?), and then came back once or twice to play it from start to finish. Both times it was a "what, that's it?" kind of reaction when I reached the end of available content, and I HIGHLY doubt anything's changed, all things considered.
Personally, I'd wait another two-three years AT LEAST before coming back, considering the dev's pace.
