In-Game Shop (Spawn)

Things that would be great for adding to the store:

More ores - Redstone's great sure but there's a whole bunch of people who I bet can't be bothered to mine stuff and it could be a great way for them to spend their taxes.

Create components - Another thing worth selling could be things that some people aren't too capable of getting in mass themselves such as alloys, brass, industrial iron and zinc and if that wasn't enough then maybe electron tubes and precision mechanisms could be worth selling?

Honestly I don't think it's more about WHAT you can buy and more so how MUCH, like if there's a wide selection of things as opposed to a few good things then it could be great for the general mass and newcomers too as opposed to highly specific things you would need in the endgame or in highly specific scenarios

I think one of the best things to add in the shop is slime ball it is quite rare and needed for create and I think most of the people won't bother to find a swamp not even a slime chunk
