So I got all of the amounts from Holoknight's runs. But I don't know the absolute minimum. Here's what I got:
7 wood -wood haxe
9 wood -wood shovel
6 wood -wood pick
32 stone
- stone bench
- stone haxe
- stone pick
- stone sword
77 wood
28 iron ore
- For Funace
11 gem
- For Chem Lab
46 stone
- factory
21 stone
- furance
Furnace
- 9 iron bars
36 sand -12 glass
42 wood (Should have that amount)
(17 fabric) 27 ichor -9 glue
4 Sail
Boat
My route is based off Jyrvn's comment for the game at Lexaloffle, which reads as follows:
"I like this game so much I used a spreadsheet to figure out a speedrun. All you need to beat the game is the following raw materials: 72 wood 45 stone 24 iron 10 gems 36 sand 12 fabric 27 ichor
The only tool you have to build is the shovel, which I recommend a wooden one. The other materials you can get with your bare hands, though it would take a lot of time. To speed things up, you can collect 17 extra stone to build the haxe, pick, and sword. Iron or better equipment is not worth it due to the cost of an anvil and three times the material.
Once you have what you need, simply build the stone bench if you haven't already and use it to build the furnace. smelt 8 iron bars and 9 pieces of glass with it. Then build the chem lab and factory with the workbench. Create 9 bottles of glue, 4 sails, and finally your boat."
Might not be perfect, but it's not bad.
If there's any month to see a category get a new record, it's probably going to be this one. There's an initiative for every single game developed by NuSan to get a new fullgame world record, and that includes Stranded Isle. Unlikely that every SI category will see a record, but there will be a much
