What it says on the tin!
Reputation ranks
Ranks only ever go up; points can drop but your rank stays.
About reputation ranksI've been trained to read descriptions of mods and modpacks with a grain of salt when it comes to claims of being inspired by or based on other games and media, as I'd come to understand that in most cases this inspiration was very loose and/or weak. But when Sunlit Valley says "A Stardew Valley experience!" it means it. A currency system, important things being ticked by days, selling crops, making mayonnaise, animal affection, and the Skull Cavern?? It's wondrous how many things have been translated from Stardew into Minecraft. Everything is implemented with great care and intention, with an eye on keeping progression (which is based primarily on your money-making potential) balanced and well-paced. My favorite pack I've played.
