Well...
You don't mine Tungsten, tungsten is a tempered form of steel.
There are copper, silver, gold, and platinum coins. One platinum coin=100 gold coins, but platinum and gold are almost identical, and you can't make coins.
You don't mine cobalt either.
Orichalum should by no means be pink. (SERIOUSLY WHO'S IDEA WAS THIS!?)
Smashing some weird altar things makes metal that is either synthetic or nonexistant appear in your world.
Only being able to mine certain things with certain tools is dumb. Really, really dumb.
You start with copper tools in tin worlds
Somehow silver, gold, and platinum, which are all precious metals and are very soft, are stronger than iron and lead, two of the heaviest naturally occurring metals.
You can somehow fit a shirt, pants, and wig over that heavy suit of armor you're wearing and look identical to what you started in.
