@Karlitoz Specter already gave the answer i would have too.
As for the Grindiness, in my opinion there will be enough later on, since equip has a durability, that means there will be an ongoing need for materials.
I also think, once the building gets the content, there will be much need for materials too, since houses needs to get repaired, otherwise they will decay.
For now we just have the base mechanics in the game with some examples to play with. There will be much more later on.
I am quite sure, we will get a burst on content during Beta and then there will nothing like "i have played whole content in 5 days."
I am very glad you like the game beside the actual lack of content
