I'll admit that I'm relatively new to the game, but I find it rather odd how restrictive the stone-age tools are, and it honestly makes for a grindy experience trying to progress through the early game. I understand and appreciate the more down-to-earth, rugged difficulty that VS has, but no stone woodsplitting? Basket and stick traps that almost never work over real world snares? For casuals like me who don't have hours on end to spare, it's almost not worth it to play the game because of how much time is required just to make it past the first tier of progress. I've tried a couple mods to mediate this, but they're only so-so stable. I've already had to sign out from my computer a couple times because when VS freezes, it really freezes.
For stone woodworking, I feel there could be certain tools restricted to Granite or some harder rocks in the same way arrowheads are restricted to flint. These tools may involve woodsplitting, hammers, and even low-level mining. There's no way someone couldn't just fasten a rock to a stick to make a hammer.
Another big example of the grindiness is getting from Stone to Copper. I've had to walk for almost half an hour in some worlds just to find nuggets of copper, and panning is almost as bad. It almost feels like VS is missing something - a tool or tools that are advanced stone that aid in getting to copper a bit more reliably then panning an entire biome of gravel for nuggets. They wouldn't even need to be an insta-fix for copper, but make it a bit more reliable. For example, maybe patches of dirt that have low-levels of ore. The only way to extract the nuggets is to smelt the blocks, leading to a slow but reliable source of ore. This method has ties in the real world as a primitive but effective means of capturing actual nuggets of ore, and I feel would fit well in gameplay.
Overall I feel like the early game could use some TLC. I know I'm not alone in this observation either, and "grindy" is a description I hear tossed around often when discussing early game. Like I said, I enjoy the more realistic gameplay of VS, but early game is actually less realistic due to how few things we can actually do to progress.
