Most games give crafters the shaft. There's no real art to pushing a button and having an item pop out, especially when today's modern MMO design heavily favors "quick crafting." Crafting is an afterthought to most games, or something that players can do to both pass the time and perhaps offer an alternative to buying items from the shops.
Then there's Final Fantasy XI. The game equipped with a crafting system so complicated, people still have arguments about how the game calculates success 6 years after its American launch. A crafting system so complicated, some people like to refer to it as "voodoo crafting."
