The crafting is what got me to look into animal crossing more as a game to pick up. I am glad it has crafting. It gives more to the game. However, there could be some improvements (Bulk crafting and a recycling system).
It is insane to have to click craft 30 times for 30 clams to get 30 bait. I mean if we had the option to buy the bait at Nooks I would so totally throw bells at that (or even Nook Miles) simply because of the time it takes to craft multiple bait.
Also it would be helpful for bulk crafting for other supplies too. Getting a bunch of sticks in your inventory. No problem, just bulk craft them into something before selling them to get a little more bells.
Maybe they would give us an upgrade on the workbenches? I mean I kinda assumed the size and type of workbench would have different perks but they don't. None of them allow bulk crafting. The only difference functionally is that one takes up less space than the other.
Someone in another thread mentioned having a recycling system. It would make sense to have one with a crafting system. This would be pretty helpful and nice. Disassemble, to an extent, something you don't want or need anymore and make it into something else.
On a completely different note, it would be cool to see an expansion on items made from old cans. I don't know what past games had, but It would be cool to see a wind spinner things or windchimes made from old cans.
