I've played through the "story" if you will and there's not much left to discover, unless I start over and romance someone different or aim for the Joja-ending, and still I come back to my farm, making wine, shoving goat-cheese into my lovers face and throwing my baby up in the air hoping she'll learn how to fly. It's just something peaceful to do to stress down and escape the stress of the world. While the rest of the game really is 5-star material it's this stress down thing that really cements it as a 5-start experience.
Humor, gameplay, story, what else can you desire? Among the best balanced games I played in my childhood, Nox was never too hard to be fun, but neither too easy to be boring. Also, the interwoven storylines you get from all three classes makes replaying the game to see all the different storylines a must. Even today worth the price!
