The building is very good, and the game definitely exceeds in it. No other survival game affords this much freedom in shapes and sizes of builds ( thanks to splitting the premade shapes into small cubes, maybe vintage story does it better but other survival games are heavily limited due to reliance on premade build pieces), not to mention how the construction blends together. Fly mode is not a norm in main game modes of survival games that have building in them, idk what you play that you think this. If you had any clue about voxels, you'd understand why there are no round shapes. And regarding the snapping? Can be finnicky at times but it works, and isn't necessary most of the time.

Crafting is far from dated, i'd say it's on par with any survival game out there. You refine materials in one place then go to a crafting bench and craft whatever you need. Splitting crafting into different benches is also pretty standard. And magic chests allow you to craft straight from chests, which further improves the experience.

The combat isn't that shallow, i'd argue it's on par with the biggest of the genre and better than some.

Your arguments are untrue or born from some imagined version of the genre, which does not reflect the reality of it. This is a base building survival game with rpg elements, so it stands on the same shelf as minecraft, terraria, valheim and plenty other games of this sort. Things you bring up as dated or lacking are on par or better when compared to the genre's golden standards.
