What a finished save needs
In Stardew Valley 1.6.x the in-game completion score is the perfection tracker. It is hidden until Qi's Walnut Room opens at 100 golden walnuts. Platform achievements on Steam, PlayStation, and Xbox are a separate list. Perfection uses the in-game goals.
The heavy rows are shipping (15%), friends (11%), and then five rows at 10% each: the Gold Clock, monster goals, Stardrops, cooking, crafting, and fish. Walnuts and skill levels are 5% each. The four obelisks are 4%.
Museum, rare items, and the farm
The museum is both a perfection neighbor and a set of tools. Forty donations earn Treasure Trove. Sixty bring the Rusty Key and, with it, Krobus's 20,000g Stardrop. Ninety-five donations earn the museum Stardrop and A Complete Collection.
Donate an Ancient Seed before you ship or plant the last one. Gunther's return pack is the Ancient Fruit crop. Keep a Dinosaur Egg for the incubator as well as the museum shelf. The egg is on the artifact list. The Prismatic Shard is a museum mineral with a 2,000g base price, and it is also a loved gift for most villagers.
Seed packs at 5, 10, 15, and 35 donations are cauliflower, melon, starfruit, and pumpkin. The Crystalarium arrives at 50 minerals. Those are the farming payouts inside the gallery. The full milestone list is the rewards page.
The long lists
Use the collections tab as the checklist. Ship one of each Farm & Forage item (154). Catch every fish on the Fish tab with a rod or a crab pot (72). Cook every recipe (81). Craft every item except the Wedding Ring (149). Find all 130 golden walnuts and all seven Stardrops.
Friendships need the whole town, and Kent only returns in year 2, so a year-1 perfection score is short by design. Datable villagers stop at 8 hearts for this row. The gift rules for Abigail, Haley, Sebastian, Leah, and Penny are on their character pages.
If a row is expensive rather than missing, Fizz sells 1% for 500,000g after you have opened the tracker once. Fourteen of those waivers cost less than building the obelisks and the Gold Clock.
