As an idea I think it would be great to make a category extension where you need to place every single survival block as feinberg did a few months ago. Then there could be like a sub-extension where you need to find naturally and then mine every possible block (as an example, if u want to get diamond block you would need to go for a mansion and then find it alredy placed on a secret room)(I've alredy tried to make somethin like a guide that can tell you every single block that u need to mine at every structure: https://docs.google.com/document/d/1mujAWnKHbF5cMht8zquF2jy9kHNplomhz6_C4MmOZFE/edit?usp=sharing ). At the end of the run, the player will show his stats to prove the run is valid.
